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!
