Introduce shared/state.ts as a service-locator so popup components
(item-detail, item-form, trash, devices, settings, etc.) work in both
the popup and vault tab bundles. Both entry points register themselves
as the host; components import from shared/state instead of popup.ts.
Vault.ts now delegates to the real popup components, removing ~300 lines
of placeholder renderers.

The mock in settings-vault.test.ts referenced the old function names
openGeneratorPopover and closeGeneratorPopover, which were renamed to
openGeneratorPanel and closeGeneratorPanel during the refactor. Update
the mock to use the current function names.
