Removes the phone-relay feature entirely per the Phase 11 finding
that it hit a fundamental phone-OS limitation (a browser page can't
route WiFi and cellular traffic simultaneously, no code fix possible)
- see PLAN.md for the full test writeup.
- app.py: dropped /api/dash/pending, /api/dash/file/<path>,
/api/dash/relay/config, /api/dash/relay/heartbeat,
/api/dash/relay/stop, /api/dash/relay/mark_uploaded routes and
their now-unused imports (os, send_file, abort, safe_join).
- modules/app_upload.py: dropped list_pending_dashcam_files(),
relay_heartbeat()/relay_stop()/is_relay_active(),
RELAY_LEASE_SECONDS/_relay_lease_until, and the relay-lease check
inside _upload_dashcam_files()/get_status(). Kept the chunked
upload protocol, dashcam_hash_cache/_hash_dashcam_file() (still
used by the Pi's own background uploader), and DASHCAM_CHUNK_SIZE -
none of that was relay-specific.
- templates/dash.html: removed the 'Relay via phone' card.
- static/js/dash.js: removed all relay JS (relayOneFile,
fetchChunkWithRetry, uploadChunkWithRetry, heartbeat timers,
pending-file list rendering).
- server/app.py: removed the CORS after_request hook, added solely
for the phone's cross-origin browser calls (the Pi's own Python
requests-based client was never subject to CORS).
- readme.md: dropped the phone-relay feature bullet, updated the
project-status blurb to explain the removal + point at the planned
native Android app as the real fix for that use case.
- PLAN.md: marked Phase 12 done with a verification writeup.
Verified: py_compile on all touched Python files, node --check on
dash.js, grepped all touched files for any leftover relay/RELAY
reference (none), and smoke-tested by importing app.py + hitting it
with Flask's test client - app starts cleanly, every relay route is
gone from url_map, and both / and /dash still render HTTP 200 with
zero 'relay' occurrences in /dash's HTML.
