v0.15.0 — Inventory depth (HomeBox parity) + Locations page

Rounds out Inventory toward HomeBox, and gives Locations a real home.

Inventory:
- Attach manuals, receipts, and warranty docs (any file), not just photos —
  attachment uploader now has a kind picker; WARRANTY kind added
- Richer purchase/warranty: purchasedFrom, warrantyDetails, lifetimeWarranty,
  insured (item dialog + detail facts + header badge)
- Schedule recurring maintenance from an item (creates a Task linked via
  itemId); item detail shows its maintenance with overdue flagged. Task create
  now accepts itemId/animalId

Locations:
- New Locations page + nav: browse/add/rename/move/delete the whole place tree
  (LocationManager over the existing /api/locations routes); shows plant/item
  counts per place. The spot to merge near-dupes before dropping legacy zone

Verified end-to-end against a running server (new fields round-trip, maintenance
task links to item, MANUAL attachment stored). tsc + 33 tests + build green.
