Reconnect and resume phase 5 work

[skyelaird]

This commit continues Phase 5 development by fixing numerous attribute name mismatches between modules and improving integration of the prediction engine.

Changes:

• Fixed attribute names in PathGeometry (azim_tr/azim_rt vs azim_tx_to_rx/azim_rx_to_tx)
• Fixed FourierMaps method name (set_conditions vs set_month_ssn_utc)
• Fixed solar.py to use correct GeoPoint attributes (lat/lon vs latitude/longitude)
• Updated prediction_engine.py to handle GeographicPoint vs GeoPoint conversion
• Added defaults to ControlPoint dataclass to enable instantiation
• Fixed geomagnetic field parameter mapping in prediction engine
• Fixed ControlPoint layer attribute names (e/f1/f2 vs e_layer/f1_layer/f2_layer)
• Updated README to reflect Phase 5 progress (85% complete)
• Created complete_prediction_example.py for end-to-end testing

Working:

• phase5_signal_example.py runs successfully
• Noise modeling (atmospheric, galactic, man-made)
• Antenna gain calculations
• Basic signal budget calculations

In Progress:

• Full prediction engine end-to-end integration
• CircuitMuf API compatibility
• Additional attribute name standardization across modules

The core Phase 5 components are functional. The full integration requires additional work to resolve remaining API mismatches between modules.
