Improve backup scripts with logging and remove duplicate rotation

db-backup-standalone.sh:
- Add logging with timestamps to backups/db-backup-standalone.log
- Add SCRIPT_DIR to make all paths relative to script location
- Add detailed logging for each backup step (stop, backup, rotate, start)
- Log rotation status and which old backups are removed

db-scheduled-backup.sh:
- Remove duplicate backup rotation logic (now handled in standalone script)
- Comment out cleanup code to avoid redundant operations
