Address PR #935 round-3 review:
- search/verification.py: rewrite _verify_mail_messages to batch by mailbox.
get_message triggers a server-side IMAP body fetch, so per-result verify
issued one IMAP FETCH per hit; now it calls the DB-cached list_messages once
per mailbox (mailbox_id comes from the Qdrant payload via result.metadata)
and intersects — O(unique mailboxes) light calls instead of O(results) IMAP.
- vector/mail_content.py: include Cc/Bcc in the indexed text so recipient
queries match; move MAIL_SCAN_MAX_PER_MAILBOX here (shared by scanner index
window + verifier presence window) with a note that it equals the Mail OCS
per-request max (100), so it's a fixed constant not a config knob.
- client/mail.py: clamp list_messages limit to 1..100 at the client layer.
- tests: add test_mail_content.py (exact-layout contract for build_mail_content);
rewrite the mail verifier tests for the batch-per-mailbox shape.
Left as-is: ValidationError isn't caught in the list-endpoint tools — consistent
with nc_notes_*/nc_deck_* and not a regression.

- models/mail.py: lowercase `list` generics per CLAUDE.md convention.
- client/mail.py: _ocs_get now inspects ocs.meta.statuscode (re-raises >=400
as HTTPStatusError carrying the OCS code so callers' 404/403 handling
applies) and guards response.json() against non-JSON bodies (RequestError).
- Extract the duplicated _format_addresses + content reconstruction into
vector/mail_content.py, used by both processor.py and context.py (fixes the
SonarCloud new_duplicated_lines_density gate).
- processor.py: add the missing mail_message Qdrant payload block so the
computed mail metadata (subject/from/to/cc/date_int/has_attachments/
account_id/mailbox_id) is actually stored, not dropped.
- Rename the list_messages `filter` param to `search_filter` (avoid shadowing
builtins.filter); still maps to the OCS `filter` query param.
- Docstring notes: has_more heuristic, attachment content size.
- Tests: OCS meta-failure + non-JSON client paths; initial-sync scanner tests
(tests/unit/vector/test_scanner_mail.py).
