Adds a "Local Login & Dev Users" section to docs/LOCAL_DEVELOPMENT.md
and a short pointer in services/mana-auth/CLAUDE.md so the next dev
finds the script without first hitting the "why can't I log in?" wall:
- Why it exists (no admin seed, requireEmailVerification + no SMTP)
- The 3 default accounts + password
- Single-account form + env overrides (TIER, AUTH_URL, …)
- Idempotency promise
- Prereqs (Postgres + mana-auth on :3001)
