briosandAnthony Stirling e2ea720fc8 refactor(api): replace regex literals with compiled patterns for improved performance and readability (#6511)
# Description of Changes


This pull request refactors several utility classes and controllers to
replace inline regular expression usage with precompiled `Pattern`
constants. This change improves performance, consistency, and
maintainability by ensuring that regex patterns are compiled only once
and reused throughout the codebase. Additionally, it enhances code
clarity and security in filename and SQL content sanitization.
