fix: professional profile fetch uses /me endpoint and re-fetches after save

- Use GET /professionals/me (JWT-authenticated) instead of /professionals/{uid}
  to avoid silent failures when the user_id lookup fails
- After save, re-fetch from server so fp.profesional reflects confirmed server state
  on the next page navigation
