Problem: When domain-discovery.sh is sourced directly (not via launcher),
plesk-helpers.sh wasn't being loaded because $LIB_DIR was undefined.
This caused list_all_domains() to fail on Plesk with 'command not found'.
Fixes:
1. Enhanced Plesk helper sourcing logic:
- Try $LIB_DIR first (when sourced from launcher)
- Fall back to $SCRIPT_DIR (when sourced directly)
- Ensures plesk-helpers.sh loads in all contexts
2. Added fallback in list_all_domains() for Plesk:
- Check if plesk_list_domains function exists
- If not available, fall back to directory scan
- Scans /var/www/vhosts/ excluding system directories
- Ensures domains are found even without plesk-helpers.sh
Impact: Domain discovery now works correctly when:
- Sourced from launcher (uses plesk-helpers.sh)
- Sourced directly from command line (uses fallback)
- Plesk CLI unavailable (uses directory scan)
Tested on: Plesk 18.0.61 production system
