* fix(email): use XOAUTH2 in test-connection for Google OAuth accounts
The test-connection endpoint was password-only and had no awareness of
OAuth accounts. For Google-connected accounts this caused two failures:
- IMAP: "Need IMAP host, username, and password" because imap_pass is
empty (no password is stored for OAuth accounts)
- SMTP: 535 BadCredentials because smtp.login() was called with an
empty password instead of an XOAUTH2 token
Fix: include oauth_provider and token fields in saved_body when hydrating
from the DB, then use conn.authenticate("XOAUTH2") / smtp.auth("XOAUTH2")
for Google accounts in both the IMAP and SMTP test paths, mirroring what
_send_smtp_message already does for real sends.

* test(email): add OAuth2 tests for test-connection endpoint
Covers the XOAUTH2 changes made to routes/email_routes.py:
- Google OAuth accounts must not be rejected with 'Need IMAP host,
username, and password' (no stored password for OAuth accounts)
- IMAP and SMTP test paths must use conn.authenticate('XOAUTH2')
for Google accounts
- Password accounts must still use conn.login() / smtp.login()
