Enforce permissions in API guards and retire interim access (#52)
Every route now declares its access rule explicitly and is enforced
through the shared resolution algorithm (permissions.md):

- PermissionGuard + decorators (@RequiresPondRole, @RequiresPagePermission,
  @RequiresAttachmentPermission, @AuthenticatedOnly) applied to every
  route; a route-enumeration test proves full coverage alongside
  @Public()/Site-Admin-guarded routes.
- 404/403 policy (documented in README conventions): denied reads answer
  404 (existence hiding), denied writes on readable things answer 403;
  trash views need write capability (ADR 0013).
- PermissionService resolves page/pond questions via the shared resolver,
  with an in-process pond-context cache (grants + label parents) that is
  invalidated on every grant/label-tree change and TTL-bounded as a
  multi-process safety net. Grant changes also fire pond_access_changed
  for collab revalidation (#39/#53).
- shared: pond-scope resolution (hasPondRole, canSeePond) next to the
  page resolver; grant wire schemas + GrantView.
- Owner Pond-Admin grants: migration backfill for all existing ponds,
  created transactionally with every new pond (shared + personal + seed).
- Grant CRUD under /ponds/:id/grants (pond_admin-gated) with structural
  and referential validation, last-admin protection, audit logs.
- InterimAccessService deleted; page lists, search, backlinks, phantom
  links, and trash listings are filtered per page through the resolver;
  collab tokens are now truly ro for readers.
- Fixture-matrix e2e (reader/editor/pond admin/foreign, label-deny,
  authenticated-subject, revoke-then-immediate-deny cache test).
