* feat: add STARTTLS support for SMTP proxy server
Add smtp_tls_cert and smtp_tls_key environment variables to enable
STARTTLS on the SMTP proxy server, matching existing IMAP TLS support.
Closes#249

* test: add E2E tests for SMTP/IMAP STARTTLS
- Add smtp-proxy-tls service with self-signed certs in docker-compose
- Add smtp-tls.spec.ts: SMTP STARTTLS send plain/HTML/auth tests
- Add imap-tls.spec.ts: IMAP STARTTLS login/list/select/fetch tests
- Register smtp-proxy project in playwright.config.ts
- Wait for TLS proxy readiness in docker-entrypoint.sh

* fix: enforce auth over TLS when STARTTLS is configured
- Set auth_require_tls conditionally based on tls_context presence
- Disable insecure SSLv2/SSLv3 protocols in TLS context

* fix: replace cert-gen service with inline cert generation
The cert-gen one-shot container was exiting immediately after
generating certificates, triggering --abort-on-container-exit
and stopping all services before tests could run.
Replace with an entrypoint script in smtp-proxy-tls that generates
the self-signed cert before starting the proxy server.
