Adds a «شبکههای اجتماعی» admin section + scheduler that publishes a daily
«کادر آمادهبهکار امروز» digest:
- AppSetting: social toggles, posts-per-day, editable header/footer,
per-channel bot token + chat id (Telegram, Bale), Instagram enable +
extra hashtags, proxy toggle, last-posted timestamp (+ migration).
- SocialPostService: builds today's talent digest as text, posts to
Telegram and Bale via their bot sendMessage APIs (proxy-aware), and
produces an Instagram caption + auto hashtags (role/city based).
- SocialPostWorker: posts N times/day, evenly spaced, self-paced; reads
settings live so it's togglable without redeploy.
- /Admin/Social: credentials + header/footer + posts/day, live preview of
today's message, «ارسال اکنون» button, and an Instagram caption pack
with copy button (semi-automatic — you post the image manually).
- Nav link added.
Telegram/Bale post as TEXT (per request). The Vazirmatn image card for
Instagram is phase 2 (needs SkiaSharp+HarfBuzz + a TTF font).
