v1.0.20-debug

Add Account: selecting a known provider (Mailcow, Exchange) now prefills its deterministic server settings directly and no longer forces the manual Advanced screen when a network autodiscover lookup misses. Mailcow now uses imap.:993 / smtp.:587 per the mailcow/SOGo mandate (previously bare domain). Generic/unknown providers still fall back to network autodiscover. Sideload to install.
