Approximate-location map on aggregated listings (Divar coords)

We captured Divar's privacy-fuzzed coords on RawListing but discarded them for
the listings that need them: unnamed-facility shifts/jobs dropped them (to avoid
piling on the shared placeholder) and applicants had no coordinate field at all.

- Add Lat/Lng to Shift, JobOpening, TalentListing (migration ListingApproxCoords).
- Publish stores the source ad's approx coords on each aggregated listing.
- Detail pages render the map from the listing's own coords (fallback: facility),
  and aggregated coords show as a shaded «محدودهٔ تقریبی» circle (not a precise
  pin) via _NeshanMap data-approx, with a disclaimer. Applicants get a map card
  (they had none) + the page now loads the Neshan key.

Only Divar provides coords; the map needs NeshanMapKey set in admin settings.
Existing rows get coords once reprocessed (RawListing already has them).
