- each row now shows Edit and Delete buttons (same styling as the
profiler list buttons) instead of the red X glyph
- Edit reloads the entry into the top form: the Add button becomes
Save (data-l10n updated too) and a Cancel button appears; submit
updates the entry in place, recomputing fid/parentFid and excluding
the edited row from the duplicate-path check
- Delete removes without confirmation; deleting the row being edited
cancels the edit and an earlier deletion shifts the edit index
- pysimCustomAdd renamed to pysimCustomSubmit; tests for the whole
flow; SW cache v114 -> v115.
