feat: [WD-19698] Custom ISO can_delete permission check.

[Kxiru]

Done

• Custom ISO - can delete permission implemented.
• Codebase refactor - Inkeeping with the fact that the there is a disassociation between Storage pools and volumes within the codebase in Context.
  • Split /api/storage-pools into /api/storage-pools and /api/storage-volumes and updated all imports.
  • Consequently, storageVolumes now have their own entitlements file and api file.
