🧹 Refactor: remove redundant code and simplify renderers

- Users table (UsersColumnDefs.js):
  - Remove unused quota calculations from the status renderer
  - Keep status Tag minimal; tooltip shows request count only
  - No functional changes

- Tokens table (TokensColumnDefs.js):
  - Simplify chats menu parsing from localStorage; remove redundant flags/loops
  - Remove unused variables and console statements
  - Keep error handling via showError; preserve existing operations behavior

- General:
  - Codebase tidying only; no UI/logic changes beyond cleanup
  - Lint passes successfully
