fix(admin): resolve moderation, gift, and admin-panel bugs from QA

- scam/fake: enforce mutual exclusivity (scam precedence) at TL conversion, admin command, and UI toggles; both flags could render as neither
- scam/fake flicker: persist scam/fake in the Redis user base cache so cache hits no longer drop the flags
- getSavedStarGifts: hidden (unsaved) gifts are now force-excluded for non-owner viewers; same guard for get-by-ref
- convertStarGift: map already-upgraded/owner-invalid/unavailable to a clean client error instead of 500
- channel force-settings: send only changed fields (partial patch) and re-sync toggles after reload, so one setting no longer resets another
- give gifts: removed custom collectible numbers (auto sequential only); locked sender to the system account 777000
- give gifts UI: fixed picker card spacing/right gap; static (hover-play) Lottie previews on emoji + picker to stop render lag; fixed emoji ID field overflow
