Add Images admin section for managing source image uses

New top-level nav section showing all source images in a list view
with checkboxes to edit the uses array (grid, bin) per image. Allows
correcting wrongly-tagged images without code changes.

Server PUT /api/source-images/:id was already in place; re-added the
frontend API wrapper that was prematurely removed.
