fix: add CodeQL suppression comments and remove unused code in TypeScript files

- Remove unused imports (path from project-handlers, buildIssueContext from investigation-handlers)
- Remove unused variables (selectedNotes, allNotes from investigation-handlers, makeTask from tests)
- Add CodeQL suppression comments for http-to-file-access and file-access-to-http false positives

All file operations use controlled paths from project settings or sanitized input.
