Major fixes:
- Fix script structure: load .env before defining variables
- Remove duplicate color definitions (use common.sh)
- Fix permission issue: use sudo for du command on data/db dirs
- Add fallback to 2GB if disk space calculation fails
- Improve error messages and logging
The main issue was that data/ and db/ directories are owned by
different users (http, 999), causing du to fail even with stderr
redirection. Using sudo or || echo "0" fallback fixes this.
Tested: Backup now completes successfully with proper logging
