feat(relay): add wss://relay.zapstore.dev for zapstore app kinds

Include the Zapstore relay when loading kind 32267 (app metadata)
events, since they're primarily hosted on relay.zapstore.dev for now.

Changes:
- Wrap addressLoader in loaders.ts to inject zapstore relay for
  kind 32267 pointers — covers all code paths (zaps, generic viewers,
  any a-tag referencing an app)
- Add zapstore relay to ZapstoreAppRenderer/DetailRenderer relay lists
  (for fetching releases related to an app)
- Add zapstore relay to ZapstoreAppSetRenderer/DetailRenderer when
  resolving app references from app collections (kind 30267)
