What

This pull request updates the API documentation configuration and schema table documentation to improve clarity and maintain consistency. The main changes include adding new schema members, refining table filters, and reorganizing documentation options for better structure and readability.

Schema documentation updates:

• Added AutolabelModel and AutolabelMixin to the members list in the t4_devkit.schema.tables documentation, ensuring these new schema classes are included in the generated docs.
• Updated the filters list in docs/apis/schema/table.md to exclude the new AutolabelModel and AutolabelMixin classes from certain documentation sections, maintaining the intended separation of core and auxiliary schema elements.

Documentation formatting and structure:

• Set show_root_heading: false for several schema table sub-items in docs/apis/schema/other.md to suppress redundant headings and streamline the rendered documentation. [1] [2] [3] [4]
• Refactored the mkdocs.yaml configuration for the API reference plugin to clarify and reorganize options, such as adjusting heading levels, toggling root headings, and updating display settings for class members and docstrings, leading to improved documentation structure and readability.
