Fixes the 13-item codebase health scan backlog: wraps meal-plan generation in a transaction, adds missing userId/GIN indexes, fixes an IPv6-parsing gap in the webhook SSRF guard (and an identical duplicated bug in the AI URL-import path, now consolidated onto one implementation), paginates the collections list, dedupes the AI recipe Zod schemas, wires up Stripe tier sync, rate-limits AI key rotation, gets `pnpm typecheck` actually working, and adds test coverage for the previously-untested admin/webhooks routes. Two flagged issues (collection removeRecipeId IDOR, tier-limit race) turned out to already be fixed/non-issues on inspection — noted in TODO.md rather than silently dropped.
