fix(FindAllResources): handle single-object responses without panic

[writesz]

The NITRO API returns a JSON array for most resource types, but some (e.g. nsversion) return a single JSON object. The hard type assertion on line 740:

resources := data[resourceType].([]interface{})

panics with "interface conversion: interface {} is map[string]interface {}, not []interface {}" when the value is a plain object.

Replace the assertion with a type switch that handles:

• []interface{} → existing array path (unchanged behaviour)
• map[string]interface{} → wrap in a single-element slice
• anything else → return empty slice with a warning log
