Do a codebase sweep to clean up unused variables, dead code, and obsolete comments

[AlAfiz]

Description

During the initial prototyping and hackathon phases, developers often leave behind console.log statements, commented-out old code, and unused imports. It's time to take out the trash.

Acceptance Criteria

• Run npm run lint and fix all "unused variable" warnings.
• Search the codebase for console.log and remove them (replace necessary ones with proper error logging or console.error).
• Delete any components, CSS files, or hooks that are no longer imported anywhere in the project.
• Remove block comments that say "TODO: fix this later" if they have been resolved.

Technical Details

• Use tools like knip or ts-prune to automatically find unused exports across the entire monorepo.
