Changes for M365 oAuth
- Added handler to start Microsoft OAuth Authorization Code flow (oauth_connect_microsoft_mail) with state generation/validation prep. - Added handler to test OAuth token refresh from admin UI and persist refreshed tokens/expiry. - Updated IMAP test handler to support OAuth token refresh + XOAUTH2 authentication (in addition to legacy LOGIN).
