Major overhaul of Urchin

[AlDu2407]

• Added TailwindCSS to Urchin.
• Updated Makefile to download TailwindCSS (currently only Linux is supported)
• Refactored templates to share similar logic between templates.
• Redesigned UI for Urchin.
• Added layout page shared between all sub pages.
• Added dark mode support.
• Added new renderHtml method to reduce duplicate code in go.
• Added self-designed minimalistic 'sea urchin' favicon. :D
• Added missing sites about and services.
• Added Not Found handling if a resource is requested that is not present, displaying an error message while keeping the layout page.
• Restructured static folder to include stylesheets, scripts and assets.

Hey @AlDu2407 , I wonder if you ever got a chance to add wget to the image?

Btw I think it has curl, so you could work around downloading the stuff you need on CI:

cp -r migrations tests/helpers/
if [ ! -f tailwindcss ]; then \
	wget -q https://github.com/tailwindlabs/tailwindcss/releases/latest/download/tailwindcss-linux-x64 \
		&& chmod +x tailwindcss-linux-x64 \
		&& mv tailwindcss-linux-x64 tailwindcss; \
fi
/bin/sh: 2: wget: not found
make: *** [Makefile:3[7](https://github.com/matheusgomes28/urchin/actions/runs/11663344344/job/32471628007?pr=97#step:4:8): install-tailwindcss] Error 127

Hi @matheusgomes28 ,

is there a way for you to remove the line in the Dockerfile, that removes wget from the build image? I think afterwards the pipeline will succeed. And afterwards you should be able to review the entire code.
