Update budget-planer version and dependencies; enhance backend process management

- Bumped the version of the budget-planer package from 0.1.0 to 1.0.0.
- Updated dependencies in Cargo.toml to their latest versions for improved stability and security.
- Refactored backend process management to improve termination logic, allowing for non-blocking cleanup during window close and app exit events.
- Implemented background execution for database migrations and server startup to prevent UI blocking.

These changes enhance the application's reliability and user experience by ensuring better management of backend processes and up-to-date dependencies.
