feat(stalk): remove dead mobile-legends, free-fire, tiktok, instagram

Audit live-probed all 8 stalk upstreams today. 4 alive (github, youtube,
genshin enka, twitter fxtwitter). 4 dead with no free alternative reachable
from VPS: mobile-legends (gempaytopup /stalk-ml now 405), free-fire
(discordbot.freefirecommunity dead 404), tiktok (WAF -> login page, no
rehydration data), instagram (mollygram captcha; i.instagram requires
login/rate-limited 401). All free alternates probed dead (onrender FF 404,
freefireapi.me 404, i.instagram 401 require_login, m.tiktok 403).

Keep 4 alive: github, youtube, genshin, twitter. stalk.rs now clippy-clean.
