feat(annotations): Add tags and Auto-tag selected in the selection bar

The Images selection bar gains the concept's Add tags and, beside it,
Auto-tag selected (D85). Add tags starts the image-tags Activity job with
the dialog's comma-separated names; Auto-tag selected reuses the Tag image
model panel (server defaults, Suggestions count) without Generate, refuses
a model that is not downloaded, and either starts the job (Apply
automatically) or walks the selection one Tag image dialog at a time
(Review each image, D90). Busy, model-busy and refused starts toast why;
the selection stays; a finished job's files are read again.
