Increment 5 — send.
- SmtpSender (Angus Mail; password/XOAUTH2) builds a MimeMessage and sends over
SMTP/SMTPS. New OutgoingMessage + SmtpParams.
- MailConnectionFactory now resolves both IMAP and SMTP params (shared credential
and token refresh); MailRepository.sendMessage.
- Compose screen wired to send: From account (a selector when there are several),
To with device-contacts autocomplete (ContactsContract, runtime READ_CONTACTS),
Cc, Subject, Body, with progress and error handling.
- Reply from the reader prefills To and a "Re:" subject (compose route gains optional
to/subject args).
- Tests: GreenMail SmtpSender unit test. assemble/test/lint green; verified end-to-end
on the Android 17 emulator — composed a message, sent it over SMTP to a local
GreenMail server, and it round-tripped back into the inbox on re-sync.
