Introduced `DirectoryForSaving` for managing directory paths persistently. Integrated the new setting into relevant modules, ensuring the selected directory is saved and loaded across sessions.
Bumped the application version from 0.7.0 to 0.8.0 in `main.go`. This prepares the app for the new release and reflects recent changes or improvements.
This commit removes outdated dependencies and adds updated versions of required modules in the `go.sum` file. The changes ensure the project uses the latest compatible releases, improving stability and maintaining compatibility with current updates.
Migrated from GORM to bbolt for lightweight key-value storage, better aligning with project requirements. Updated repository methods to utilize bbolt's native APIs and removed dependencies associated with GORM.
