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

Removed all 3 any types and replaced with proper TypeScript types.

Changes:
- Replaced as any with Partial<ReturnType<typeof useSettingStore>>
- Used as unknown as for partial mock subgraph (114+ missing properties)

All tests passing (3/3), 0 typecheck errors.

Part of #8092
