Refactor SQL cleanup by introducing reusable constants

Introduce `QUERY_CLEANUP_REGEX` and `TRIM_CHARACTERS_REGEX` constants to improve code readability and reduce redundancy. Replace hardcoded regex strings with these constants in SQL trimming and cleanup operations. This makes future maintenance and updates to these patterns simpler and more centralized.
