fix: add Uri.EscapeDataString to service URL path interpolations

Browse Source 
VmService, ContainerService, StorageService, and SnapshotService now wrap
user-controlled string parameters (node names, storage names) with
Uri.EscapeDataString() in URL path construction, preventing path traversal
or encoding issues. Integer parameters (vmid) are left unwrapped.
