feat: Refactor data migration functionality and introduce cloud migration dialog

- Removed the DataMigration.vue component and integrated its functionality into KvDatabaseCard.vue.
- Added a new CloudMigrationDialog.vue component for handling cloud data migration.
- Updated KvDatabaseCard.vue to include a button for initiating local migration and to manage the visibility of the new CloudMigrationDialog.
- Cleaned up the DataProviderSettingsCard.vue by removing old data migration UI elements.
- Enhanced user experience by providing a more streamlined migration process with clear category selection and progress indication.
