Add Plesk MySQL authentication support to database discovery

Browse Source 
Problem: Plesk MySQL requires password authentication
  User report: "ERROR 1045 (28000): Access denied for user 'root'@'localhost'"
  Result: 0 databases detected on Plesk servers

Root Cause:
  Plesk stores MySQL admin password in /etc/psa/.psa.shadow
  All MySQL queries were using passwordless 'mysql' command
  This works on cPanel (uses ~/.my.cnf) but fails on Plesk

Solution: build_databases_section() in lib/reference-db.sh
  1. Check if running on Plesk and /etc/psa/.psa.shadow exists
  2. Read admin password from file
  3. Build mysql_cmd variable with credentials
  4. Use $mysql_cmd for all database queries

Changes (lib/reference-db.sh):
  Lines 161-166: Added Plesk credential detection
  Line 168: Use $mysql_cmd for SHOW DATABASES
  Line 179: Use $mysql_cmd for size calculation
  Line 184: Use $mysql_cmd for table count

Impact:
  ✅ Database discovery now works on Plesk
  ✅ Backwards compatible with cPanel/InterWorx/Standalone
  ✅ No performance impact (password read once)

Status: Ready for testing on Plesk server
