Zac 2615143c6d feat(mam-api): finish per-project authz on the deferred routers
Phase 1 scoped only projects/assets/bins and left recorders, sequences,
imports, comments carrying TODO(authz) markers. A scoped editor/viewer could
still read and mutate those across every project. This closes the gap using
the existing authz.js helpers — no open TODO(authz) markers remain.

- recorders: param('id') resolves project + view baseline, requireRecorderEdit
  on PATCH/DELETE/start/stop, GET / filtered by accessibleProjectIds, POST /
  asserts edit on the target project (null project = admin-only)
- sequences: same param pattern + requireSequenceEdit on PUT/:id,/clips,conform
  and DELETE; GET//POST/ assert on the query/body project
- imports: POST /youtube asserts edit on the body projectId
- comments: router.use guard resolves project via the asset (view to read, edit
  to write); also fixes the author bug (req.session.userId -> req.user.id, which
  was always NULL so comments had no recorded author)
- capture: intentionally any-logged-in (shared hardware, asset scoped on
  registration) — TODO replaced with a rationale note

Security fixes from review of this change:
- recorders POST /:id/start: a per-take projectId override could route a live
  asset into a project the caller lacks edit on — now asserts edit on the
  override target
- sequences PUT /:id/clips: spliced asset_ids weren't checked, so an editor
  could pull in (and via GET /:id leak signed proxy URLs for) assets from a
  project they can't access — now every clip asset must belong to the
  sequence's project; pre-transaction queries moved inside try/catch so a DB
  error returns 500 instead of hanging the request

- tests: recorders-access, sequences-access (incl. cross-project clip guard),
  comments-access (incl. author-id regression)

// authz: intentionally any-logged-in (no per-project scoping). This is a thin
// proxy to shared capture hardware with no project_id of its own; the resulting
// asset is scoped when it's registered via the /assets route. Gated by the
// global requireAuth in index.js, like the rest of /api/v1.
