* feat(auth): add email verification login flow with 401 auto-redirect Replace the old OAuth-based login with email verification codes: - Backend: send-code / verify-code endpoints, verification_codes table (migration 009), rate limiting, Resend email service - Frontend: two-step login UI (email → 6-digit OTP), auth store with sendCode/verifyCode - SDK: ApiClient gains onUnauthorized callback; 401 responses auto-clear token and redirect to /login - Fix login button staying disabled due to global isLoading state Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(auth): add brute-force protection, redirect loop guard, and expired code cleanup - VerifyCode: increment attempts on wrong code, reject after 5 failed tries (migration 010) - onUnauthorized: skip redirect if already on /login to prevent infinite loops - SendCode: best-effort cleanup of expired verification codes older than 1 hour Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(auth): add master verification code for non-production environments Allow code "888888" to bypass email verification in non-production environments to simplify development and testing workflows. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(auth): add personal access tokens for CLI and API authentication Add full-stack PAT support: users create tokens in Settings, CLI authenticates via `multica auth login`. Server stores SHA-256 hashes only. Auth middleware extended to accept both JWTs and PATs (distinguished by `mul_` prefix).
