feat(mobile): Add Partner Sharing Avatars to Timeline and Info Cards

[x24git]

This Feature adds user avatars to the timeline for both partner sharing, and shared albums. The avatar uses the user's avatar image (if one is set) or the server's information is used to make an avatar using the user's assigned color and first letter of their name.
(In the screenshot below, the partner's icon is an Orange 'T')

This is an optional configuration that adds a new setting in the Photo Grid section of the settings.

Additionally, storage information is now shown in the image details card. For partner sharing it will show which partner it belongs to. For other images, it provides a text description and existing storage icons if the photo is local, remote, or merged (backed up). This can be useful if the storage icons are hidden.

I am working on implementing a similar feature set on the web app to ensure consistent experience

Implements
#7608 (actually for the web but the original PR publisher writes that he will consider a web version)

Yeah, the plan was to put mobile and web together in one PR but ran into some issues getting it done efficiently on the web side, so I split the work. Should have the web implementation done shortly, and that would implement #7608 almost exactly like you mocked it up.

Cleaned up commit history and rebased to main, resolving merge conflicts.

PR #12413 implements the same feature set on web.
