Format Java .properties configuration

Validate application settings and normalize them as key-value pairs while preserving nested structures through dotted keys and numeric array indexes.

Formatting tips

• Use dotted keys for nested objects
• Use indexes such as items[0] for arrays
• Escape separators that belong inside keys
