Fix clippy warnings in WpDeriveParamsField macro

Address clippy issues identified in cargo clippy --tests:

Changes:
- Remove redundant enum variant prefixes (AppendQueryMethod variants)
- Collapse nested if statements in is_wp_date_time_option method using let-chain patterns
- Update all enum variant references and test assertions
