fix(jetbrains): map custom provider delete action to disconnect

- Route ProviderListAction.DELETE through the existing disconnect() handler
  so the trash-icon action actually removes the custom provider
- Add the missing settings.providers.delete bundle key referenced by
  ProviderListRows
- Preset a default id/name/URL when adding a new custom provider without an
  existing config to edit
