Listings returned every row regardless of ownership: GET /files, /tags,
/pools and /categories exposed other users' private items (while the
single-item GET correctly returned 403), and the pool file operations
(GET /pools/:id, /pools/:id/files, add/remove/reorder) skipped ACL
entirely, so any authenticated user could read and rewrite anyone's
private pool.
- List queries now filter to rows the caller may see (public, owned, or
granted can_view) via a shared SQL condition; admins bypass. The viewer
identity is taken from the request context by the service and passed to
the repository in the list params.
- Tag/Category/Pool single-item Get now enforce CanView (File already did).
- Pool Get/ListFiles require pool view; AddFiles/RemoveFiles/Reorder
require pool edit.
Adds regression tests for private-by-default listing (hidden / public /
granted / admin) and for pool operations rejecting a non-owner.
