fix(profiles): Don't show unsaved changes dialog when nothing was edited

In create mode, the init block pre-filled _currentState with a default
name but left _initialState empty. The hasUnsavedChanges() check saw
the non-blank name as a change, triggering the dialog on back press
even without user edits.

Set _initialState to match _currentState defaults in create mode and
unify the comparison logic to always use current != initial.
