PR #1874 by ksylvan: refactor: replace interface{} with any across codebase

• Replace interface{} with any in slice type declarations
• Update map types from map[string]interface{} to map[string]any
• Change variadic function parameters to use ...any instead of ...interface{}
• Modernize JSON unmarshaling variables to any for consistency
• Update struct fields and method signatures to prefer any alias
