Fix audit findings: bugs, security, perf, content

Bugs:
- setup-wsl: fix broken /img/WSL/* image paths (now bundle-relative;
  images were broken on the published post) + better alt text
- pi-docker-swarm: remove broken missing cluster.webp reference
- archetypes/posts.md: fix malformed {{ }} template so 'hugo new' works
- rename arrstack/arrstack.md -> index.md so it's a proper leaf bundle
- static/admin/config.yml: fix 'htpps' -> 'https' site_url typo
- fix silently-dropped <placeholder> text (unsafe=false dropped them):
  wrap <distro>/<username>/<user>/<version>/<ip address> etc in backticks
  across setup-wsl, securing-ssh, pi-docker-swarm, mc-server-on-docker

Security:
- render-link.html: add rel=noopener noreferrer to external target=_blank
- extend-footer.html: fix rel='me' trapped in class attr (broke Mastodon
  verification); add proper rel/target
- static/admin/index.html: pin Sveltia CMS to 0.172.4 via jsDelivr + SRI

Performance:
- hugo.toml: ignoreFiles for *.aseprite/*.bak (stop shipping source art;
  non-page files 23 -> 13)
- video shortcode: preload=metadata; image shortcode: loading=lazy decoding=async
- sws.toml: drop SPA page-fallback so missing paths return real 404 (404.html)

Content/SEO:
- normalize tag casing (HomeLab/RemoteAccess/SSH/HUGO -> lowercase),
  fix 'prodcutivity' typo, arrstack tags:[""] -> [], add welcome description
- delete stray index.md.bak

-description: "Ever wanted to build a Minecraft server in docker !! Start here"
----
-
-## **Introduction**
-
-Minecraft is a great game that becomes even more enjoyable when played with
-friends. One of the best ways to do this is by setting up a dedicated server.
-This guide will help you do just that!
-
-Setting up and running a Minecraft server does not require a lot of resources,
-but based on my experience, allocating more resources significantly enhances
-performance. Especially when you start to add mods and increase player count.
-
-## **Prerequisites**
-
-- Docker
-- Docker Compose
-
-See [Pi Cluster](/posts/pi-docker-swarm/)
-for more information about my docker setup.
-
-## **Requirements**
-_Requirements Gathered from [here](https://minecraft.fandom.com/wiki/Server/Requirements/Dedicated#Unix_.28Linux.2C_BSD.2C_macOS.29)_
-
-### **Minimum (1-5 Players)**
-
-- Intel Pentium 4 or AMD Athlon based CPU
-- 512 MB RAM
-- 2 GB Storage space
-
-### **Recommended (10-15 Players)**
-
-- Intel Core or AMD K8 based CPU
-- 3 GB RAM
-- 16 GB Storage Space
-
-### **Optimal (20+ Players)**
-
-- Intel i5/i7 or AMD Ryzen 5/7 Based CPU
-- 6 GB RAM
-- 35 GB Storage Space
-
-**My opinion**:
-
-I personally went with the **optimal** settings as I wanted to run mods as well
-as have the capacity for ~10 players. This gives the server breathing room.
-
-However if you will be runing no mods or a few light weight mods and only a few
-players then there really is no need to go higher than 3-4 GB.
-
-## **Building the Container**
-
-Lets get started on building the Minecraft server
-
-1. **Create a directory for the Minecraft server files**:
-```bash
-# Make the folder
-mkdir minecraft-server
-# Enter the folder
-cd minecraft-server
-```
-
-2. **Create an environment file for the Docker Container**:
-- The _.env_ file allows us to specify variables used in the build process.
-```bash
-# Create a .env file
-touch .env
-# Open in a text editor
-vim .env
-# Enter the following variables
-CONTAINER_NAME=minecraft-server
-SERVER_MEM=4096 #change this to your desired value (in MB)
-SERVER_JAR=<downloaded-server-file>.jar # Minecraft server jar file. Change this later
-```
-
-3. **Create the _docker-compose.yml_ file**:
-```bash
-# Create the file
-touch docker-compose.yml`
-# Open in a text editor
-vim docker-compose.yml
-```
-- _docker-compose.yml_ is the spec of our Minecraft server.
-  - Build a docker image using context . and pass some ARGS.
-  - Attach volume .server-data, where Minecraft's files will be stored.
-  - Open network ports to  access to the Docker container
-  - Give the docker container a name
-  - The container will always restart unless we tell it to stop.
-
-```yaml
-services:
-  minecraft-server:
-    build:
-      context: .
-      args:
-        SERVER_MEM: ${SERVER_MEM}
-        SERVER_JAR: ${SERVER_JAR}
-    volumes:
-      - .server-data:/server
-    ports:
-      - 25565:25565 # Game
-      - 25575:25575 # RCON
-    container_name: ${CONTAINER_NAME}
-    restart: unless-stopped
-
-volumes:
-  server-data:
-```
-
-4. **Create the _Dockerfile_ file**:
-
-- requested in docker-compose.yml build stage as context .
-- The _Dockerfile_ is the spec for software running inside the container
-
-```bash
-# Create the file
-touch Dockerfile
-# Open the file in a text editor
-vim Dockerfile
-```
-- We use the [eclipse-temurin:21](https://hub.docker.com/_/eclipse-temurin) image to provide the java JRE
-  - Use the required java version for the version of Minecraft you are running
-- Collect the ARGs from the .env file
-- Set the environment variables
-- Set the working directory to /server which on our local system is .server-data
-- Run the minecraft server jar with the ENV variables
-
-```Dockerfile
-FROM eclipse-temurin:21
-
-ARG SERVER_MEM
-ARG SERVER_JAR
-
-ENV SERVER_MEM=${SERVER_MEM}
-ENV SERVER_JAR=${SERVER_JAR}
-
-WORKDIR /server
-
-CMD echo "Minecraft Server is starting\n" && java -Xms128M -Xmx${SERVER_MEM}M -jar ${SERVER_JAR} nogui
-```
-
-## **Setup the Server files**
-
-We’re almost there, just a few steps to go.
-
-When you try to start the container, you might encounter the following error:
-```bash
-Minecraft Server is starting
-
-Error: Unable to access jarfile server.jar
-```
-This happens because we haven't downloaded the server jar file yet. Let's do
-that now
-
-1. **Create a folder in the minecraft-server folder called .server-data**:
-
-```bash
-mkdir .server-data
-cd .server-data
-```
-
-2. **Download a Minecraft server jar file**:
-  - [Vanilla Minecraft Server](https://www.minecraft.net/en-us/download/server)
-    - Right click the green link that says minecraft_server.<version>.jar and copy the link address
-    - Download with: `curl -o server.jar <link you copied here>`
-  - [Fabric Mod loader server](https://fabricmc.net/use/server/)
-    - Select the Minecraft version, Fabric Loader Version and the Installer Version of your choice. I tend to go with the latest.
-    - Download with: `Copy the curl command under CLI download`
-
-3. **Go back to the root minecraft-server folder**
-
-```bash
-cd ..
-```
-
-4. **Edit SERVER_JAR in .env with the name of the .jar you just downloaded**:
-```bash
-# Open in a text editor
-vim .env
-# Enter the following variables
-CONTAINER_NAME=minecraft-server
-SERVER_MEM=4096
-SERVER_JAR=<downloaded-server-file>.jar # Change this to the name of the .jar you downloaded
-```
-
-5. **Run the container to generate necessary files like 'eula.txt'**:
-```bash
-docker compose up
-```
-you will see something like this:
-```bash
-minecraft-server  | Starting net.minecraft.server.Main
-minecraft-server  | [18:05:50] [ServerMain/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.
-minecraft-server exited with code 0
-```
-
-6. **Accept the EULA**:
-
-```bash
-# edit eula.txt in a text editor
-vim .server-data/eula.txt
-# change `eula=false` to `eula=true`
-eula=true
-```
-
-7. **Make any additional changes you want**:
-- Notable files:
-  - **server.properties** - Configure server name, game mode, world type etc…
-  - **ops.json** - server operators (can be set in-game)
-  - **whitelist.json** - players allowed to join the server (can be set in-game)
-
-## Run the Minecraft Server
-
-1. **Run the container in detached mode**:
-```bash
-# The -d flag allows the container to run in detached mode, i.e., in the background
-docker compose up -d
-```
-
-```bash
-# monitor the logs as the server starts. Use CTRL+C to exit
-docker logs minecraft-server --follow
-# If you see the following lines, your server is up and running:
-     [18:17:01] [Server thread/INFO]: Time elapsed: 25529 ms
-     [18:17:01] [Server thread/INFO]: Done (34.571s)! For help, type "help"
-```
-
-## **Conclusion**
-
-Congratulations! You've successfully set up a Minecraft server. Now it's time
-to play!
-
-There are many exciting possibilities from here, such as installing mods or
-creating scripts to manage the server. Enjoy your Minecraft adventures!
