feat(cities): cities are a tree again, as legacy's; old dashboard permissions merged (PERS-02, PERM-01)

Cities (owner: as legacy)
- City.parentId (self relation) replaces the flat `province` label; the
  migration turns each label into a parent row («استان …») first, so nothing
  is lost.
- Admin pickers are legacy's tree (CityTreeSelect): the top level, the
  country, is a heading. The city form and grid get «والد».
- Restored legacy _getP: a city without its own percent takes its
  ancestor's. Restored the omde-customer form's city → percent autofill.
- Import copies legacy parents; delete refuses a city with children; a
  parent loop is refused.

Permissions (owner approved the deletion)
- dashboard / dashboard.omde / dashboard.tak rows become dashboard.view,
  then are deleted.
- Import maps them the same way: legacy types 102, 104, 105, 108 and 135
  had lost the dashboard.
