oauth

okay so this is annoying because i already did oauth support for Forumtest https://tangled.org/@whey.party/forumtest/commit/2ff6b79adb285cbbc5d843bc30926cee003602db and forumtest used to use the exact same auth system as red dwarf so like its mostly just a backporting issue but also it would be nice to support both methods of login at once for easier developer environments but also for user preference https://bsky.app/profile/isaac32767.picknit.com/post/3m2nere5qo22w
