feat(mobile): sort users alphabetically

[OdinOxin]

Description

Now displaying users in drift_user_selection and drift_album_options in alphabetically order, as already implemented in Web (#27731).
For large immich-instances it is now easier to find a specific user to share an album with.

Fixes # (issue)

How Has This Been Tested?

• Connected Debug-App to public Immich-Demo-instance and opened the share page for an album.
• Connected with own Immich-Instance and opened the album options page for an shared album.

Screenshots (if appropriate)

Unsorted

Sorted

We want the users list to be sorted ideally in the SQL query. Can you update the query with the sort instead?
