Adds :key="component" to <component :is="Body"> so opening drawer B
while A is open fully remounts (A's instance/state can't leak into B) —
a real defect for a primary shell overlay. Same-name reopen still
relies on the body reacting to prop changes (documented inline).
Companion test asserts the cross-component switch swaps the body
cleanly (A unmounts, B mounts). Addresses the Task 5 code-review
Important finding.

Adds composables/drawerRegistry.ts (boundary-safe register-by-call map:
register/resolve, zero static component imports — composables zone may
not import components, RFC-WS-GUI-REDESIGN AD-G5). Extends useRightDrawer
with resolveDrawerComponent (thin facade, prior API/tests preserved).
RightDrawer.vue: PrimeVue <Drawer position=right>, v-model:visible via a
writable computed ↔ useRightDrawer isOpen/close; title/flush read from the
open() props object (A4); dynamic <component :is> via resolveDrawerComponent
with a graceful empty state on null; #actions header slot retained. 18
unit/component tests.
