Fix all remaining cyclomatic complexity issues

Resolves the final 5 Credo cyclomatic complexity issues by:

1. packet.ex: Create get_field_value/2 helper function
   - Replaces all `data[:field] || data["field"]` patterns
   - Reduces complexity in put_equipment_fields (11 -> 9)
   - Reduces complexity in put_phg_fields (12 -> 9)
   - Reduces complexity in put_standard_parser_fields (11 -> 9)

2. query_builder.ex: Use SQL fragment for weather_only query
   - Replaces multiple Elixir `or` operators with single SQL fragment
   - Reduces complexity from 10 to within limits

3. packet_utils.ex: Use SQL fragment for weather check query
   - Replaces multiple Elixir `or` operators with single SQL fragment
   - Reduces complexity from 11 to within limits

All 71 Credo issues now resolved:
- 14/14 warnings ✓
- 14/14 design suggestions ✓
- 40/40 refactoring issues ✓
- 3/3 code readability issues ✓

100% Credo compliance achieved!
