chore: update backup configurations and directory structure

- Modified `.gitignore` to exclude all files in the `/data/` directory.
- Enhanced `BACKUP.md` with customization options for backup storage paths and updated database path configurations.
- Updated `docker-compose.yml` to reflect new paths for database and backup storage.
- Adjusted `Dockerfile` to create a dedicated backups directory.
- Refactored `BackupService` to utilize environment variables for backup paths, improving flexibility and reliability.
- Deleted `dev.db` as it is no longer needed in the repository.
