fix: 🐛 correct media type handling for @DeleteMapping with @RequestBody

- CLOSE ISSUE #1133
- Remove redundant DELETE method check in bodyMediaType logic, which caused incorrect OpenAPI spec generation when `@DeleteMapping` is used with `@RequestBody`
- Simplify query parameter handling by removing unnecessary DELETE-specific condition
- Update copyright year from 2024 to 2025 in affected files
