New IranEstekhdamListingSource: reads the site monthly ad sitemaps (sitemap-ads.xml -> sitemap-ads-YYYY-M.xml), keeps only ad URLs whose Persian slug names a clinical role (veterinary/non-clinical excluded), then extracts each ad title + description (+ phone). These are employer ads at NAMED facilities, so they directly improve the unknown-facility problem the classifieds content has. Wired in like Medjobs: AppSetting toggles (IranEstekhdamEnabled/MaxAds/UseProxy) + EF migration, SettingsService persistence, admin Settings UI, and DI registration. Off by default; the medical-gate validator + AI auditor + junk filters screen results downstream. Note: e-estekhdam / jobinja / jobvision are JS-rendered SPAs whose ad lists are not in static HTML, so they need API reverse-engineering (a separate effort), not this static-scrape path.
