Resi cue countdowns on ProPresenter and in Companion

The Resi -> ProPresenter bridge, its installer and site kit, and the
Companion module resi-studio-cues, as running at North Attleboro.

Bridge (resi_to_propresenter.py)
- Follows a Resi decoder's playhead and keeps ProPresenter's NextCue timer
  counting down to the next cue; optional cue name as a stage message, sent
  once per cue (ProPresenter flashes it on every send) and off by default.
- Playhead estimate no longer learns a cadence from the partial first gap
  after a start, so a 30s Resi doesn't read as paused half the time.
- Backs off on 429, holds 2 min before retrying a failed startup login, and
  logs Resi's actual reason (wrong password, USER_LOCKED, rate limit).
- --setup asks for the login, decoder, ProPresenter and timer.

install_bridge.sh installs it as a login service (outside ~/Documents,
which launchd may not read); make_kit.sh builds the kit for another site.

Companion module resi-studio-cues 0.1.4 (source/, package committed)
- Same playhead fix; login and request hold-off (15s doubling to 5 min);
  a 401/403 on a fresh session is a permission, not a reason to sign in
  again; init never fails on a Resi problem, so Companion can't restart it
  into a login loop.

Tests: test_playhead.py, test_stage_message.py, test_rate_limit.py and
source/backoff_test.js run offline; test_end_to_end.py drives a real
ProPresenter and refuses to run without an explicit flag.
