Contact reveal modal: click phone/contact on cards and detail pages

Adds a lazy-loaded contact modal. Any element with data-contact-type +
data-contact-id (the «📞 تماس» button on shift/job/talent/recommendation cards,
and the contact CTA on the three detail pages) opens a modal that fetches the
listing's numbers from a new GET /contact endpoint and renders them with click-
to-call links. Numbers are loaded only on click, so they never sit in list-page
HTML (privacy / anti-scrape). The endpoint logs the same Apply interest signal
for shift/job that the old inline-reveal POST did, and falls back to the
facility phone (or Divar source link for talent) when an ad has no own contacts.

Verified locally: GET /contact?type=shift&id=1 → {title, contacts:[{value:
'021-82032000', href:'tel:...'}]}, and the modal opens and renders on the shift
detail page.
