feat(docs): improve mkdocstrings configuration

Enhance Python documentation generation with updated mkdocstrings settings.

This commit:
- Enables `dataclasses`, `unpack_typeddict`, and `griffe_fieldz` extensions for richer API documentation.
- Sets member filters to `public` for clearer visibility of exposed APIs.
- Introduces `overloads_only`, `show_signature_type_parameters`, `parameter_headings`, and `type_parameter_headings` for more precise and structured signature and parameter display.
- Removes the `docstring_inheritance.griffe` extension due to a reported crash.
- Activates `skip_local_inventory` for potential build performance improvements.
