fix: lint cleanup, remove tests for later rewrite, ES compat

- Fix all Ultracite lint errors on changed source files (0 remaining)
- Remove project.test.ts and use-personal-organization.test.ts (to be
  rewritten when implementation stabilizes)
- Replace .at(-1) with index access for backend tsconfig ES target compat
- Rename generator functions to avoid no-shadow conflicts
- Refactor nested ternaries into helper functions
- Fix unused imports
