steve a837b25d73 feat(admin): Phase 4 — doctor, admin completeness, and bubbletea TUI
Adds the admin/diagnostics surface from SPEC §7.2:

- doctor [--account]: per-account IMAP + (RW) SMTP connectivity/auth checks via
  new mail.CheckIMAP/CheckSMTP (connect+auth only, no mail). Exit non-zero on any
  failure; secrets never printed.
- store.UpdateAccount: partial edit, re-encrypts password/secrets only when a
  non-empty value is supplied (blank keeps existing). RecentAuditFor(account).
- config set/get (validates audit_retention_days), audit list [--account][--limit],
  account edit (flag partial-update) / remove [--yes].
- internal/tui: bubbletea AccountForm with pure, fully-tested Fields (validation +
  store.Account assembly + edit prefill). init / bare `account add` / `account edit
  --name X` drop into the TUI; flag forms remain for scripting.

Built test-first; full suite green incl -race. Validated live against the mxlogin
(password) and Gmail (app-password) accounts. Live validation caught a real bug:
doctor authenticated with empty passwords because it iterated ListAccounts (which
strips secrets) — fixed to re-fetch via GetAccount, locked in by a regression test.
