/**
 * Tests for SpoolBuddyAmsPage Phase 13 changes — full component-render integration.
 *
 * Renders the actual SpoolBuddyAmsPage with mocks and asserts on the new wiring
 * introduced by Phase 13:
 * - P13-1d:  SlotActionPicker shows Local-Assign action on empty slots (local mode)
 * - P13-4:   AssignSpoolModal receives spoolmanEnabled prop from parent
 * - P13-5:   unlinkSpoolMutation invalidates all 5 dependent query keys
 * - P13-6a:  spoolmanSlotAssignmentsAll + spoolmanInventorySpoolsCache queries fire when spoolmanEnabled
 * - P13-6b:  Slot-assigned-only Spoolman spool produces a fill bar
 * - P13-6c:  SlotActionPicker hides Link button when slot has SpoolmanSlotAssignment
 *
 * SpoolSlot tiles render as <div onClick=... title="AMS Slot N">; tests target
 * them via getByTitle which is a stable, semantic selector. Buttons inside the
 * SlotActionPicker are addressed by their visible text (translated via the
 * mocked react-i18next; t-fallback returns the second arg).
