feat(quality_dashboard): populate section items (Task 3)

_fetch_section_items pulls top-5 open records per type, ranked
overdue-first by oldest create_date. _build_item shapes each row
with id/name/customer/subtitle/urgency/open_action. _resolve_partner
defensively walks partner_id -> job_id.partner_id -> ncr_id.partner_id
per type. _build_subtitle generates the human-readable second line.

Tests cover empty list, 5-cap on 8-record set, and required item
keys (id/name/customer/subtitle/urgency/open_action).
