Instead of playing whack-a-mole with individual fields, this implements a
proper whitelist approach that only allows fields defined in the Packet schema.
- Created PacketFieldWhitelist module with all 78 valid packet fields
- Filters out ANY field not in the schema, preventing future errors
- Handles both atom and string keys
- Includes debug helpers to identify filtered fields
This definitively fixes packet insertion failures by ensuring only valid
database fields are passed to Repo.insert_all, regardless of what the
APRS parser sends.
