Clean Pydantic BaseModel objects out of API docs

References and relevant issues

Closes #964

Description

Pydantic v2 causes every EventedModel-based API page (Viewer, Camera, Colormap, ...) cluttered with inherited BaseModel members. Here we use conf.py to hide them from the tables and the autodoc Details sections.
napari's own overrides (model_dump, json, model_json_schema) are kept. IMO this is desirable because the API docs aren't just for "everything" but should be a bit more opinionated, especially for most users that don't need these.

Dropped from the tables:

• 20 methods — 11 deprecated v1 (copy, dict, construct, parse_*, schema*, validate, from_orm, update_forward_refs), 8 v2 (model_construct, model_copy, model_dump_json, model_parametrized_name, model_rebuild, model_validate*), and model_post_init
• 5 attributes — model_computed_fields, model_config, model_extra, model_fields, model_fields_set

Is there a way to add at least a collapsed section with this, or at least a link to the pydantic docs?

This is fully generated by Deepseek, but I managed to inject that into such docstrings:

Thoughts?
