feat(NEP-82): Netzwerk-Tick-Handler mit Storage-Disks, Importer/Exporter, AdjacentInventory

Browse source 
- NetworkTickHandler: Vollständiger Tick-Zyklus mit Power-Check, Inventory-Propagation,
  Importer- (pull), Exporter- (push) und Disk-I/O-Logik
- NetworkInventory: Aggregiertes Netzwerk-Inventar (ConcurrentHashMap-basiert)
- DiskDriveManager: Verwaltet StorageDisk-Slots pro Drive-Position (max 8)
- StorageDisk: 1k/4k/16k/64k Tiers, priority-basiertes Insert/Remove
- StorageSlot: Einzel-Slot mit 64 Stack-Limit pro Item-Typ
- AdjacentInventory: Simulierte World-Storage für Importer/Exporter
- NetworkManager: logging refactor (lazy init + JUL fallback), resetForTesting(),
  inventory+powered Felder, BFS rebuild-Fix (clear lookups vor BFS)
- DiskDriveUI: Echte Disk-Collection via DiskDriveManager statt stub,
  format/eject/priority mit logging
- Tests: 18 NetworkManager-Tests (BFS, cable split, 3D propagation, full layout),
  5 NetworkTickHandler-Tests (inventory ops, powered toggle)
- build.gradle.kts: JUnit 5 Test-Config + Jacoco Report
