Fix role + contact mislabels seen on a live iranestekhdam ad

(1) Specialist guard: the AI sometimes labels a clearly-specialist ad («پزشک متخصص گوش و
حلق و بینی»، «فلوشیپ»، «فوق تخصص») as «پزشک عمومی», so an ENT post published as
«استخدام پزشک عمومی». When the primary role is GP but the ad text names a specialist, swap
it to «پزشک متخصص» (the subspecialty stays as a tag).

(2) Phone type: the landline regex 0\d{2,3} also matched 09xx MOBILE numbers and labeled them
«تلفن ثابت». Iranian landline area codes are 0[1-8]xx (021/026/…), never 09 — restrict it so
mobiles are no longer mislabeled as landlines.

Both apply to new ingests; existing mislabeled rows correct on turnover/reprocess.
