fix: correct configuration loading order in BaseCliCommand

- Load examples/config.{driver}.php first when PDODB_DRIVER is set
  and no explicit environment variables are provided
- This ensures examples use the same config file that createExampleDb() uses
- Fixes MariaDB example failure in CI where examples/config.mariadb.php
  was loaded after buildConfigFromEnv() returned null
- Skip examples config if environment variables are explicitly set
  (allows CI/user override while preserving examples functionality)
- Remove duplicate examples config check at the end of function
