fix: Improve type safety in asset metadata

  validation

  - Replace any type with proper Record<string,
  unknown> | undefined
  - Fix nodeId type check to support both string
  and number types
  - Remove redundant object type checks in type
  guard
  - Remove unused isValidUuidV4 function from
  uuidUtil
  - Simplify metadata validation logic
