Remove FlagColor model/API/tests from this PR so schema and EF model stay aligned with the structured-fields migration. FlagColor remains in the follow-on PR that adds its migration.
Persist primary/extra services, service notes, free-text POC, and
tech/vendor notes on create/patch/board/detail instead of embedding
them in description.
Expand LifecycleStatus (EnRoute, OnSite, Rescheduled, Pending, PendingQuote) and WorkOrderType (Reactive, AddOn) to match the frontend prototype. Add FE label round-trip via LifecycleStatusMapper/WorkOrderTypeMapper, update derived fields, mutation rules and board unscheduled filter, and reactivate [Authorize] on WorkOrderController. Fix pre-existing dayGroup test expectation.
