The Files page could only list a collection if the operator already
knew its name and typed it in. No "browse known collections" affordance,
no backend endpoint listing collections.
Closest approximation without new backend: pull registered files-trigger
collection_globs from the existing triggers list and surface them as:
- a <datalist> on the collection input for autocomplete
- chip buttons under the form that one-click set the input
Empty state copy points the operator at the Triggers tab. Backend
endpoint to list known collections directly is still a v1.1.10+ task.
Styling uses the F-U-004 :root tokens so it inherits the dark theme.
AUDIT.md anchor: F-U-003 (frontend-only; backend endpoint deferred).
