Fix #66: Auto-create database file if it doesn't exist

Auto-create database file if it doesn't exist

Description

This PR fixes issue #66 where the node crashes if the database file hasn't been created before launch.

Changes

• Added directory creation logic to ensure the database parent directory exists
• Added automatic migration execution when connecting to the database
• Added proper error handling and logging for the database initialization process

Impact

With these changes, the node will automatically create the database file and directory structure if they don't exist, then apply the required migrations to set up the database schema. This improves the user experience by eliminating the need for manual database file creation.

Testing

• Tested with non-existing database file and directory
• Verified migrations are properly applied to new database
• Ensured existing database files continue to work as before

Fixes #66

Thank you very much for your contribution!

Your solution works but I think we should handle this slightly differently following the suggestion here SeaQL/sea-orm#283 (comment). I would propose that you revert the current changes and instead we modify this line to be:

            let path = ctx.config().datadir().db().join("scroll.db?mode=rwc");

This allows for custom database backends to be used via custom config.database_path and provides desired behaviour for default case. Would be great if you can test this out please.
