chore: release NanoShare 1.20.0

- Bump the application version from 0.1.0 to 1.20.0 using the project version scheme.

- Trim pyproject dependencies to direct root packages only and let uv.lock keep the resolved transitive set.

- Update the quart_common submodule to include the latest wide-event session context handling.

- Adjust NanoShare wide-event middleware expectations for the new session payload shape.
