feat(fusion_plating_shopfloor): HoldComposer shared OWL service

Plan task P1.6. Modal hold-creation form: reason picker, qty split,
optional photo (camera input on mobile), description, mark-for-scrap
toggle. Calls /fp/workspace/hold (added in P1.9). Reason list kept
client-side, keep in sync with fusion.plating.quality.hold.hold_reason.
