feat(messaging): sync draft emails and edit them in the thread composer (#22178)

Stop excluding drafts from sync across all three providers (Gmail DRAFT
label, Microsoft/IMAP Drafts folder) and add an isDraft boolean field on
Message so drafts are queryable by the API and AI agents.

Drafts render in the thread with a Draft tag; clicking one opens the
existing reply composer pre-filled with the draft's recipients, subject
and body, and Send reuses the existing send-email flow.
