chore(database): drop youtube_tokens table

[arpitgupta1214]

Summary

YouTube auth fully migrated to Composio (chat#1719, api#494). The youtube_tokens table is no longer read or written; CASCADE cleans up the trigger, indexes, RLS policy, and FK to accounts.

Test plan

• Apply migration on a Supabase preview branch
• Verify youtube_tokens is gone (\d youtube_tokens)
• Confirm chat YouTube connect/disconnect still works against the preview project
• Run pnpm update-types in chat/api/tasks against the migrated project; ship the regen as follow-up PRs

Summary by cubic

Drop the legacy youtube_tokens table now that YouTube auth is fully handled by Composio. CASCADE removes the table and its trigger, indexes, RLS policy, and FKs to keep the schema clean.

• Migration
  • Apply the Supabase migration on a preview branch.
  • Confirm youtube_tokens is gone.
  • Verify YouTube connect/disconnect still works against the preview project.
  • Regenerate DB types with pnpm update-types in chat/api/tasks (follow-up PRs).
