fix(SEC-WEB-26+29): Remove console.log + fix formatTime error handling

- Remove debug console.log from workspaces page and teams page
- Fix formatTime to return "Invalid date" fallback instead of empty string
  when date parsing fails (handles both thrown errors and NaN dates)
- Export formatTime and add unit tests for error handling cases
