Rename in 91045a1 was only partially reverted by later commits, leaving
~20 UI spots calling the project entity "Client" while table headers
already said "Project". Reverted all of them plus the /clients/:id
route (now /projects/:id canonical again, nothing was live yet).
Also: stop tracking .env.backfill (had a live admin password/token
committed - rotate those credentials), remove stale pre-redesign
layout.md superseded by REDESIGN-LAYOUT2.md.
- Remove recursive directory size calculations (single Seafile API call per list)
- Remove 'Used in this location' usage display
- Fix move using v2 per-type endpoints instead of broken batch endpoint
- Send entry type from frontend for correct move routing
