[Facilities] Public facility pages + ratings & reviews

New /Facilities/Details public page: verified badge, info, Neshan map + directions, the facility's open shifts & jobs, and a complaint form; facility cards on /Facilities link to it. Ratings & reviews: Review model (1-5 stars + comment, one per user/facility, unique index, migration); logged-in users rate/review on the facility page; average + count shown in the header and the review list; admins moderate (hide/delete) at /Admin/Reviews.
