refactor: replace all explicit any types with proper TypeScript types

Backend resolvers: typed enrichArticle/enrichVideo/enrichModel with DB
and $inferSelect types, SQL<unknown>[] for conditions arrays, proper
enum casts for status/role fields, $inferInsert for .set() updates,
typed raw SQL result rows in gamification, ReplyLike interface for
ctx.reply in auth. Frontend: typed catch blocks with Error/interface
casts, isActiveLink param, adminGetUser response, tags filter callback.
