feat(cli): add MySQL support for schema introspection

Introduces a MySQL-specific introspection provider to support pulling existing database schemas into ZenStack.

The implementation includes logic for mapping MySQL data types to ZenStack types, handling auto-incrementing fields, and parsing MySQL-specific enum definitions. It utilizes dynamic imports for database drivers to minimize the CLI footprint for users not targeting MySQL.
