* fix(migrations): make Phase6 completion slide-over migration idempotent
Use IF EXISTS / IF COL_LENGTH guards and explicit EF migration metadata
so partial environments can apply Phase 6 safely.
* feat(locations): add sites options endpoint and vendor contactName
Expose GET /api/locations/sites for the WO create wizard and include
vendor contactName on dropdown responses.
* feat(work-orders): add structured service notes POC and vendor fields
Persist primary/extra services, service notes, free-text POC, and
tech/vendor notes on create/patch/board/detail instead of embedding
them in description.
* fix(work-orders): make stacked tip build for CI quality gates
* fix(work-orders): align stacked services with CI build
* fix(work-orders): keep FlagColor out of structured-notes slice
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.
