refactor(core): ♻️ move student equipment to sandbox/equipment

- relocate equipment implementation and styles from pages/student-page to pages/sandbox
- add new src/pages/sandbox/equipment.ts and equipment.css
- update imports to reference sandbox/equipment in sandbox-page.ts, simulation-manager.ts, sync/storage.ts, and sync/sync-manager.ts
- remove legacy src/pages/student-page/student-equipment.ts and student-equipment.css to eliminate dead code and avoid duplicate components
- align equipment placement with SandboxPage structure
