Add account verification, improve login error messages, fix "account removal" and more

[MV-GH]

• Refactor login and improve the error messages
• Changes to the drawerheader so that it still shows user when site retrieval fails, so that users don't think their account is removed
• Add account verification checks (With snackbar UI interaction)
• Add warning icon in drawer header if account is in bad state
• update baselines profiles
• update benchmarks deps
• Refactor Account? to Account, with AnonAccount as Unit
• Prevent unnecessary API call to /site when starting up
• Clean up some TODOs
• Update gradle
• Make our HttpClient as singleton (do not recreate it)

Account verification checks:

• Check if device has internet capability
• Check if instance is alive
• Check if account is deleted
• Check if jwt is still valid
• Check if site is successfully retrieved
• Check if email required is done
• Check if account application approved

Not sure if email required check and account approval are needed even at this point.
Regarding the banned check I need some more info, see matrix

If there are any missing checks let me know rather add it here than later in SQL migrations

Currently it checks accounts in HomeActivity on startup and in every action requiring a account
It invalidates the account when the /site retrieval fails or when a authenticated user /site User portion is missing (JWT invalid).

This ended up being much bigger than I originally anticipated.

I did notice that the instance alive check fails in emulators due them not having ICMP support. Not sure what to do yet with that

Hmm apparently some cellular providers also block ICMPs, ig it is not reliable enough to use it. What else should I do? check a API endpoint??

I am now using a different method to calculate instance is alive, which does not suffer from the issue with the previous method.
