Conflicts:
- `app/models/account.rb`:
Upstream refactored this file a bit, moving validation limits to constants.
We already had a similar change, although with different constant names.
Updated to match upstream's code.
The following files were also modified accordingly:
- `app/views/settings/profiles/show.html.haml`
- `spec/requests/api/v1/accounts/credentials_spec.rb`
Conflicts:
- `spec/controllers/api/v1/accounts/credentials_controller_spec.rb`
Conflict due to glitch-soc's different note length handling.
Ported the changes in `spec/requests/api/v1/accounts/credentials_spec.rb` instead.
