This commit fixes two bugs in the cold-standby script:
1. Support digits in COMPOSE_PROJECT_NAME
The script was stripping digits from COMPOSE_PROJECT_NAME, while
backup_and_restore.sh (fixed in a71d991c) correctly supports them.
Added '0-9' to the tr character set to align behavior.
2. Support docker-compose.override.yml on remote
Lines 172 and 287 explicitly used '-f docker-compose.yml' which
causes Docker Compose to ignore docker-compose.override.yml even
when present. Changed to 'cd && compose' pattern (matching line 296)
to auto-discover override files.
Impact: Users with custom volumes/services in override file would
experience silent failures - volumes not created, images not pulled,
data syncing to wrong locations.
Both fixes ensure cold-standby works correctly with standard Docker
Compose conventions and user customizations.
