feat: Add conditional pages (404, loading, error, maintenance, rate limiting)

[ch1kim0n1]

Added conditional pages for:

• page not found (404)
• error page (and a lil guide on what to do)
• Maintence page
• loading page (just in case)
• status page to show if meteormate is up

All of the pages follow MeteorMate's web design.

Also added rate limiting on registration & login in order to prevent system overloads by repeatedly inputting wrong information. (assuming its done on purpose after 10th time)

Just a couple changes to take a look at here. If you can get these few things adjusted we can get this merged asap :) Great work as always!

@ch1kim0n1 I noticed we now have auth error mapping both in authErrors.ts (from your first PR) and again in sanitizeErrorMessage inside the error boundary (in this PR). They look like they’re trying to solve the same problem but in different layers. Might be worth centralizing this so we don’t end up with two diverging mappings over time. Do you maybe want to go ahead & rebase w/ main and centralize the two? Otherwise though, all your fixes look great!
