Rentiva v4.58.2 — Transfer City Filter + UI Polish
TransferSearchEngine had no location filter — a search for an İstanbul route returned vehicles parked in Ankara and Antalya. This release adds city-based vehicle matching (route origin's city), reusing the rental module's 3-layer hybrid filter (vehicle → vendor inheritance → global default) via a new expand_to_city mode. Plus a batch of UI/content polish: KPI spacing on list-table pages, dashboard card heights, About page hardening, and Vehicles calendar parity with the Bookings page.
