Trading Journal — Spring Boot

A restructured version of the original Node.js/Express Trading Journal, rebuilt with:

• Backend: Java 17 + Spring Boot 3 + Spring Data JPA
• Database: SQLite (file trading_journal.db, created automatically)
• Frontend: Same HTML/CSS/JS from the original project (unchanged)
