Maurice 6a3d4b1281 fix(budget): stop receipts deleting files, and share the upload path
Attaching a receipt no longer lets the budget domain delete one. Trashing the
file was reachable from the REST route, the MCP tool and the plugin RPC, none
of which check file_delete, and a receipt id is any file on the trip, so anyone
who could edit an expense could trash a document they were not allowed to
touch. A concurrent edit could do it by accident: the client sends the full set
of receipt ids from a snapshot taken when the form opened, so saving an expense
someone else had just attached a file to moved that file to the trash. Removing
a receipt now removes the link and nothing else.

The link row is treated as shared, because it is. One row can tie a file to a
place and to an expense at once, so the sync clears only the receipt half and
leaves the rest, the foreign key is SET NULL rather than CASCADE, and a receipt
already in the trash keeps its link so restoring it comes back attached.

The upload and its rollback moved into one module both shells call. It was
copied into six places, and all six rolled back with the permanent-delete
route, which only accepts a file that is already in the trash and therefore
answered 404 every time: a failed save left every uploaded file on the trip,
attached to the expense, and the next attempt uploaded another copy. It now
trashes first, keeps the pending files for the retry, and says so when a file
could not be removed instead of swallowing it.

Escape in the receipt viewer no longer closes the expense form behind it, the
download fallback uses a real accent class rather than a utility that does not
exist, and the upload indicator is actually switched on.

Tests: the receipt link behaviour on both service paths, the four new branches
in the files service, the upload module, and the viewer.
