Fix live updates for /info/:call page by sending all packet fields

Update the PostgreSQL notify_packets_insert trigger to send all necessary
fields when broadcasting new packets. Previously only minimal fields were
sent (id, sender, lat, lon, inserted_at), which prevented the info page
from displaying complete packet information during live updates.

The trigger now includes:
- Position data (lat, lon, altitude, course, speed)
- Symbol data (symbol_table_id, symbol_code)
- Device data (device_identifier, path)
- Metadata (received_at, comment, raw_packet)
- PHG data (phg_power, phg_height, phg_gain, phg_directivity)
