Fix CakePHP 5.3 compatibility in ModelPropertyFactory

Use public API methods instead of __debugInfo() for accessing column
metadata and primary key information. In CakePHP 5.3, TableSchema
stores columns and constraints as objects rather than arrays, causing
__debugInfo() to return Column/Constraint objects instead of arrays.

Changes:
- Replace __debugInfo() with getColumn() for column default value
- Simplify isPrimaryKey() to use getPrimaryKey() public API

Both getColumn() and getPrimaryKey() are stable public API methods
that return arrays for backwards compatibility.

Fixes mixerapi/mixerapi-dev#159
