Fix Codacy static analysis warnings

- Exclude package-lock.json via .codacy.yml
- Remove unused variable wsHtml
- Remove unused parameter e in mouseenter handler
- Fix unnecessary escape chars in regex patterns
- Convert BRACKET_PAIRS and hipBodies to Map to fix Object Injection Sink
- Use .charAt() instead of bracket notation for string indexing
- Add nosemgrep annotation to safeHTML innerHTML (trusted content only)
