chore: remove supabase dependency

[Xazin]

Supabase has been sunsetted and is not being used in the client.

I've removed the code related to supabase (mostly from the Flutter side and in language files). - If we plan to add it back, it remains mostly untouched in the backend as of yet, although there is a lot of unused strategies and edge-cases that litter the authentication logic.

For backwards compatibility, I didn't remove the EncryptSecretScreen and surrounding logic.

There are some pub deps that can't be updated because of constraints set by the supabase_flutter version. Now, we can remove those dependency overrides in dependency_overrides.

I wasn't aware 👍 I will take a look.
