feat(01-08): rewire app.py lifespan and deps.py to use build_pipeline

- app.py: replace inline component wiring with build_pipeline(env=cfg.env)
  - Store processor as app.state.processor (and backwards-compat pipeline_components)
  - RuntimeConfig replaces get_settings(); MAVLink stop() on shutdown
- deps.py: get_flight_processor prefers app.state.processor from lifespan
  - Falls back to build_pipeline() for test contexts without lifespan
  - Per-request repo/streamer swap preserved
