fix(email): support env:// refs in smtp_from/smtp_user/imap_user and preserve email config through v0 migration

Browse source 
- Change SMTPFrom, SMTPUser, IMAPUser from plain string to SecureString
  so env:// references are resolved at runtime (previously passed literally
  to SMTP/IMAP, causing auth failures)
- Add Email field to channelsConfigV0 and ToChannelsConfig() so the email
  block is not silently dropped when loading a version-0 config (the
  migration was resetting enabled=false regardless of config contents)
