feat(console): ensure tempest serve supports routes with file extension

[blackshadev]

What

• extends tempest serve with a router script to control what it will serve as static file and what will continue through tempest
• The old/current implementation doesn't allow routes with known file extensions (eg .json) to hit tempest even if the file does not exist

How to test

• Add an route #[Get('/example/{file}')] to a known controller
• run tempest serve and try accessing the route through curl http://localhost:8000/example/my_file.json
  • On my branch this will work
  • On main this will result in a 404 (given that example/my_file.json doesn't exist)

Nice, thanks! Ideally we add some tests for this, feel free to take a stab at it if you want to: #708

I can take care of it as well btw, no problem
