Notes can't be used without /e/ account

Summary

Make /e/OS Notes usable without having to log into an account.

Description

What is the feature?

As of now /e/OS Notes can only be used with the user logged into an account. We need to add a "local" mode so the user can use the app without having to log into an account, like done in /e/OS Tasks for instance.

The welcome screen of Notes now:

• explains to the user what the 2 actions proposed to them imply: Choose between syncing your notes with an existing Murena cloud account or storing your notes locally in your device (not synced).
• gives the choice between ADD ACCOUNT and USE LOCAL NOTES

The screen the user accesses to when tapping on their avatar at the top right corner now offers a third choice: Use local notes

Who will use this new feature?

Users who want to take notes on their phone but who don't have an account on which they can sync them.

Why these users would like to use this feature?

Freedom of use. /e/OS should be usable without having to create an account.
