Fix various code issues and clean up imports

[YousefAliUK]

Hey! 👋

I was going through the codebase and noticed a few things that could be improved, so I went ahead and fixed them.

What I found and fixed:

• The db.ts file was empty but being imported elsewhere, which would cause issues
• There was some unreachable code in repoAdder.ts - an if statement checking for a condition that could never be true based on the outer if
• The retry logic in fetchExtensions.ts was incrementing the counter twice, which would skip retry attempts
• A few places were using Number (the wrapper object) instead of number (the primitive type)
• There were duplicate meta tags in app.html including conflicting theme-color values
• Some async operations were missing await
• A comment said the limit was 50 but the code was actually 5

Also cleaned up:

I noticed a lot of ../../../ imports which get hard to follow, so I set up path aliases ($components, $assets, $api) to make the imports cleaner and easier to read.

Also translated some French comments to English and fixed a couple of typos.

After these changes, the type checker went from 7 errors down to 1 - and that remaining one is expected since apiKeys.js needs to be created by users with their own tokens.

Let me know if you have any questions or want me to change anything!
