docs: stop claiming pixiv, and stop claiming everything gallery-dl supports (406 step 4)

Ships with the switch-off rather than with the code removal: a doc that promises a platform the product refuses is the Install and Public Surface area's characteristic defect.

pixiv comes out of README (twice), SECURITY.md (twice), .env.example and the compose header. The stored-credential warnings now name Patreon and SubscribeStar - the accounts that usually carry a payment method.

One correction beyond pixiv. README said FabledCurator follows creators on Patreon, SubscribeStar, Pixiv "and anything gallery-dl supports". That was already false: a platform not in the registry is rejected, however capable gallery-dl is. It now names the real set, which rule 171 records: Patreon, SubscribeStar, Discord and HentaiFoundry.

The 3422 docs guards still hold - the key path and bootstrap variable are untouched.
