Make source-link listings reachable + skip uncontactable applicants

(1) The contact modal only offered a click-through link for Divar sources, so medboom/
iranestekhdam/channel listings with no inline phone looked uncontactable. Offer the source link
for ANY source («مشاهده آگهی در منبع»), for talent, shifts, and jobs alike — rescuing the dead
applicant cards that actually have a source URL.
(2) At publish, skip an applicant («آماده به کار») that has NO contact path at all — no phone, no
contact channel, and no source URL. Such a card cannot reach anyone. Existing ones drop out when
the talent reprocess button rebuilds the board.
