test: remove explicit any types from useSelectionState.test.ts

Removed all 14 any types from Pinia store mocks.

Changes:
- Replaced as any with as unknown as ReturnType<typeof store> pattern
- Removed as any from $state and _p properties (empty objects)

All tests passing (6/6), 0 typecheck errors.
