Fix stuck loading after save on profile and schedule views

- Remove fp.clear() from profile initState: if profesional is already
  loaded (e.g. navigating from schedule page) the form renders instantly
  without a spinner; if null the Consumer already shows the spinner.
- Add .catchError() so the spinner always resolves even on API failure.
- Remove redundant GET /professionals/me reload inside updateProfesionalProfileInfo:
  data is already correct from copyProfesionalWith, so the save button
  no longer waits for an extra round-trip after the PATCH.
- Wrap save button in try/finally so _saving always resets to false.
