Road to no explicit any part 8 group 5 (#8329)

## Summary
- Add `createMockLLink` and `createMockLinks` factory functions to
handle hybrid Map/Record types
- Replace `as any` assertions with type-safe factory functions in
minimap tests
- Implement proper Pinia store mocking using `vi.hoisted()` pattern
- Remove unused `createMockSubgraph` export (shadowed by local
implementations)

## Test plan
- [x] All minimap tests pass (29 tests)
- [x] `pnpm typecheck` passes
- [x] `pnpm lint` passes
- [x] `pnpm knip` passes
