4607c358ed Add ground station automation with 6-phase implementation 
Phase 1 - Automated observation engine:
- utils/ground_station/scheduler.py: GroundStationScheduler fires at AOS/LOS,
  claims SDR, manages IQBus lifecycle, emits SSE events
- utils/ground_station/observation_profile.py: ObservationProfile dataclass + DB CRUD
- routes/ground_station.py: REST API for profiles, scheduler, observations, recordings,
  rotator; SSE stream; /ws/satellite_waterfall WebSocket
- DB tables: observation_profiles, ground_station_observations, ground_station_events,
  sigmf_recordings (added to utils/database.py init_db)
- app.py: ground_station_queue, WebSocket init, scheduler startup in _deferred_init
- routes/__init__.py: register ground_station_bp

Phase 2 - Doppler correction:
- utils/doppler.py: generalized DopplerTracker extracted from sstv_decoder.py;
  accepts satellite name or raw TLE tuple; thread-safe; update_tle() method
- utils/sstv/sstv_decoder.py: replace inline DopplerTracker with import from utils.doppler
- Scheduler runs 5s retune loop; calls rotator.point_to() if enabled

Phase 3 - IQ recording (SigMF):
- utils/sigmf.py: SigMFWriter writes .sigmf-data + .sigmf-meta; disk-free guard (500MB)
- utils/ground_station/consumers/sigmf_writer.py: SigMFConsumer wraps SigMFWriter

Phase 4 - Multi-decoder IQ broadcast pipeline:
- utils/ground_station/iq_bus.py: IQBus single-producer fan-out; IQConsumer Protocol
- utils/ground_station/consumers/waterfall.py: CU8→FFT→binary frames
- utils/ground_station/consumers/fm_demod.py: CU8→FM demod (numpy)→decoder subprocess
- utils/ground_station/consumers/gr_satellites.py: CU8→cf32→gr_satellites (optional)

Phase 5 - Live spectrum waterfall:
- static/js/modes/ground_station_waterfall.js: /ws/satellite_waterfall canvas renderer
- Waterfall panel in satellite dashboard sidebar, auto-shown on iq_bus_started SSE event

Phase 6 - Antenna rotator control (optional):
- utils/rotator.py: RotatorController TCP client for rotctld (Hamlib line protocol)
- Rotator panel in satellite dashboard; silently disabled if rotctld unreachable

Also fixes pre-existing test_weather_sat_predict.py breakage:
- utils/weather_sat_predict.py: rewritten with self-contained skyfield implementation
  using find_discrete (matching what committed tests expected); adds _format_utc_iso
- tests/test_weather_sat_predict.py: add _MOCK_WEATHER_SATS and @patch decorators
  for tests that assumed NOAA-18 active (decommissioned Jun 2025, now active=False)

e00fbfddc1 v2.26.0: fix SSE fanout crash and branded logo FOUC 
- Fix SSE fanout thread AttributeError when source queue is None during
  interpreter shutdown by snapshotting to local variable with null guard
- Fix branded "i" logo rendering oversized on first page load (FOUC) by
  adding inline width/height to SVG elements across 10 templates
- Bump version to 2.26.0 in config.py, pyproject.toml, and CHANGELOG.md

4a6dddbb48 Add comprehensive test coverage for weather satellite modules 
- Created test_weather_sat_routes.py with 42 tests for all endpoints
- Created test_weather_sat_decoder.py with 47 tests for WeatherSatDecoder class
- Created test_weather_sat_predict.py with 14 tests for pass prediction
- Created test_weather_sat_scheduler.py with 31 tests for auto-scheduler
- Total: 134 test functions across 14 test classes
- All tests follow existing patterns (mocking, fixtures, docstrings)
- Tests cover happy paths, error handling, and edge cases
- Mock all external subprocess calls and HTTP requests
