ui: edit/delete buttons for custom files

- 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.
