Dev Infrastructure - Mailhog, Messenger & E2E

Overview

Added Mailhog for local email capture, an auto-consuming messenger worker container, a debug email endpoint, and Playwright-based E2E test infrastructure with automatic re-authentication.

What Changed

Mailhog Container

• New Docker service captures all local email (SMTP on port 1025, web UI on port 18025).
• MAILER_DSN=smtp://mailhog:1025 set as the dev default across all environment files.
• No emails leave the local development environment.

Messenger Worker Container

• messenger-worker Docker service auto-consumes the async queue on container start.
• Hourly restart via --time-limit=3600 and crash recovery via restart: unless-stopped.
• Memory bounded at 256M. No need to manually run bun run dev:consume.
• Worker logs: docker compose logs messenger-worker -f

Debug Test Email Endpoint

• GET /debug/test-email endpoint (dev environment only) for verifying email delivery.
• Optional query params: ?to=...&subject=...
• Sends a test email through the configured mailer, viewable in Mailhog.

Error Email Reduction (PR #702)

• Fixed DateTimeField::setHelp(null) TypeError in ProjectCrudController.php:1995 - now checks before calling setHelp.
• Fixed GET /refresh-milestones-preview returning 405 - endpoint now accepts GET and returns JSON.
• Eliminated 35 of 225 error emails found during Mailhog review.

Playwright Auto-Reauth (PR #704)

• E2E tests detect session expiry and automatically re-authenticate via /debug/test-login.
• auth-storage.json persisted between runs, removing the need for manual e2e:save-admin-form-auth.
