Fixes from testing email search (docs/enhancements-2026-07-07.md):
- New `folders` agent command lists the account's mailboxes (name,
delimiter, selectable), INBOX first, so agents can discover archived
mail outside INBOX.
- `search --all-folders` sweeps every selectable mailbox; each hit
carries a `folder` field, `skipped_folders` reports mailboxes the
server refused, and --limit caps visible results across the sweep.
The sweep deliberately skips EnsureFolderBaseline so a read-only
search never mutates list --new state.
- Empty search results include a generic `data.hint` with next steps.
The hint is a fixed constant per mode, so the invisibility invariant
holds: absent and policy-filtered mail produce byte-identical
envelopes (codified in TestSearchEmptyHintIndistinguishableFromFiltered).
- Skill and user docs: document `--text` full-text search as
best-effort (server-dependent); recommend --subject-contains/--from.

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.

Pass 0 (unlimited) to m.Search so the mail layer returns all matching
headers; the existing post-filter loop already caps at the caller's
limit, mirroring ListCmd. Add TestSearchLimitCountsVisibleOnly to prove
filtering happens before the cap.

Thread uidv through setup's return value (new uint32 before the cleanup
func) so AckCmd no longer makes a redundant SelectFolder round-trip that
silently returned 0 on failure and recorded acks under the wrong
UID-validity epoch. All four callers updated; read-only callers ignore
the value with _.
