chore: fix lint errors and reduce warnings across codebase (#234)

* chore: fix lint errors and reduce warnings across codebase

- Fix noExplicitAny catches in backend routes and plugins
- Fix noNestedTernary issues in backend services
- Add keyboard event handlers for useKeyWithClickEvents in frontend
- Disable noImportantStyles rule in biome.json
- Fix formatting errors across all changed files
- Fix test file lint issues

Closes #233

* fix: restore any types in test files for TS compatibility

* fix: revert Auth.tsx dependency array changes that caused infinite re-render

* fix: null-safe user.username access in AppContext dependency array
