Improved database initialization

[emilkrebs]

• improved database initialization to increase memory efficiency

[Copilot]

Pull request overview

This PR refactors database initialization to improve memory efficiency by moving from lazy initialization to eager initialization at application startup. The database instance is now created once in main.ts and exported for use across the application, eliminating the need for the getNoteDatabase() function and its associated service file.

Changes:

• Replaced lazy database initialization with eager initialization in main.ts
• Removed the database-service.ts file and replaced all getNoteDatabase() calls with direct access to the exported noteDatabase instance
• Extracted copy button logic into a reusable CopyButton component to reduce code duplication
• Updated dependencies to newer versions and reformatted configuration files
