apply/save button does not actually work in the config(workflow.py)

[Osayi-ANL]

The Apply/Save button in the Workflow config dialog does not behave as a proper save action. Edits to the config tree are auto-persisted to the database / active profile on every cell change via the itemChanged signal handler, so:

• By the time the user clicks Apply/Save, the values are already saved.
• There is no visible indication that edits are pending.
• Closing the window mid-edit does not revert in-progress changes — they have already been written.

Acceptance criteria

• when apply/save is hit the data should be saved
• Add an indicator when there is an unsaved edit (e.g., asterisk in dialog title, highlighted Apply/Save button, or dirty marker on edited tree rows).
• If the user closes the window mid-edit, in-progress edits must not have been saved (changes are discarded, or the user is prompted to save/discard/cancel).
