admin: gift granting, collectible attribute/number control, and Layer 228 moderation tools

Admin console additions (Layer 228):
- Give Gifts: dedicated tab with sorted Lottie/TGS gift picker + inline form; grant any catalog gift to a user/channel from 777000 (no charge)
- Upgraded/collectible delivery: mint a unique gift with admin-selected model/pattern/backdrop and custom number, or random/auto (DB FK + UNIQUE(gift_id,num) enforce invariants)
- SCAM/FAKE flags for users/channels (migration 0136) with configurable profile warning (TELESRV_SCAM_WARNING/TELESRV_FAKE_WARNING)
- Support toggle, force channel settings incl. gigagroup (migration 0137), username management, cosmetic color/emoji-status
- Emoji admin tab (custom emoji list + document IDs + Lottie/TGS preview)
- Bot management; soft UI / dark theme
Wired through Router -> admin.Service -> adminapi -> BFF -> React panel (en/zh/ru).
