Refresh generated Python app-server SDK types (#18862)

This is the first step in splitting the Python SDK PyPI publish work
into reviewable layers: land the generated SDK refresh by itself before
changing packaging mechanics. The next PRs will make the runtime wheel
publishable, then wire the SDK package/version pinning to that runtime.

## Summary
- Refresh generated Python app-server v2 models and notification
registry from the current schema.
- Update the public API signature expectations for the newly generated
kwargs.

## Stack
- PR 1 of 3 for the Python SDK PyPI publishing split.
- Follow-up PRs will handle runtime wheel publishing mechanics, then
SDK/package version pinning.

## Tests
- `uv run --extra dev pytest` in `sdk/python` -> 51 passed, 37 skipped.
