Roll TripAccessGuard onto the remaining trip-scoped controllers

assignments, budget, collab, accommodations, reservations and booking-import
drop their copied requireTrip/requireEdit helpers for the guard. Status codes and
bodies are unchanged.

places is deliberately NOT converted, and that is the finding of this PR rather
than an omission. Its e2e suite documents that the body pipe answers 400 ahead of
the trip 404 — a parity shift somebody made on purpose — and a Nest guard always
runs before the pipe, so converting it silently reverses that ordering. The first
attempt also dropped the permission check on DELETE, which the integration suite
caught as a 200 where a 403 belonged. places keeps its in-handler check, and
README now says why so the next person does not rediscover it the same way.

collab applies the guard per handler for the same reason files does: its note-file
upload route would otherwise be refused before multer had read the body, and a
response sent mid-upload destroys the socket.

Two coverage notes. The per-domain thresholds are regenerated because deleting a
well-covered helper lowers a file's ratio without anything becoming less tested —
the drops are 0.4 to 1.2 points across six domains and match the helpers removed.
And the atlas integration suite gets the same admin1-bundle warm-up the unit suite
got: ATLAS-013 was paying 3.1s for the one-off decompression inside its own 5s
budget, which is why it only ever failed under load. It now runs in 116ms.

+## TripAccessGuard, and the one domain it does not fit
+
+`permissions/trip-access.guard.ts` resolves `:tripId` once per request, answers 404
+"Trip not found" for anything the user cannot reach (never 403 — that would confirm the
+id exists), and hands the row to the handler through `@Trip()`. `@RequirePermission`
+carries the same action string the domain services pass to `checkPermission`.
+
+Two limits are worth knowing before rolling it onto another controller, because both
+were found the expensive way:
+
+- **A guard runs before the body pipe.** Any route whose DTO validation is expected to
+  answer 400 *ahead of* the trip 404 cannot use it. `places` is exactly that case — its
+  e2e suite documents the pipe-first ordering as a deliberate parity shift — so places
+  keeps its in-handler `requireTrip`, and that is not an oversight.
+- **A guard also runs before interceptors.** On a multipart upload route, a 404 sent
+  while the client is still streaming destroys the socket, so the caller sees
+  ECONNRESET instead of the 404. The three upload routes (files, collab note files,
+  places) keep their own check for that reason; their controllers apply the guard per
+  handler instead of on the class.
+
+The services keep `verifyTripAccess`/`canEdit` regardless: most of their callers are
+`*.mcp.ts` tools, which never pass through an HTTP guard.
