[Enhancement]: Serve static files statically

[mrjvs]

Checked Existing

• I have checked the repository for duplicate issues.

What enhancement would you like to see?

Currently we have a router called web.ts that serves static files with custom headers and such.
This needs to be replaced with a express-static module:

• It will improve caching
• Correct content-type will then be sent
• No longer need to add routes per file-type, everything in the folder will be served

There's two approaches:

• Have a express-static per subdomain.
  • Pro: hard-boundary between platforms
  • Con: harder to debug what file you're receiving if it's bugged, cuz of dynamic routes.
• Have one express-static and have the platform as part of the filepath: /ctr/my-styles.css
  • Pro: Easy to trace what static files are coming from where, just a single folder to serve
  • Con: Assets for different platforms can be requested from any subdomain

Would appreciate some input from @ashquarky on which approach to take

Any other details to share? (OPTIONAL)
