Update API docs for v2026.1

[matthew-white]

This PR is to track changes that we need to make to the API docs for v2026.1. If a PR makes a change to the API and simultaneously changes the API docs, then that change doesn't need to be listed here.

⚠️ If there is a breaking change to the API, an issue should be filed with pyODK.
