Migrate to kittycad 0.4.7 API for commands_ws

[Copilot]

The kittycad 0.4.7 upgrade introduced a breaking change: commands_ws() now accepts a single CommandsWsParams struct instead of 10 individual parameters.

Changes

• Updated modeling-session/src/lib.rs to use CommandsWsParams struct with field initialization
• Used ..Default::default() for unset fields (api_call_id, pool, post_effect, pr, replay, order_independent_transparency)

Before:

.commands_ws(
    None, fps, None, None, None, 
    show_grid, unlocked_framerate, 
    video_res_height, video_res_width, webrtc,
)

After:

.commands_ws(kittycad::modeling::CommandsWsParams {
    fps, show_grid, unlocked_framerate,
    video_res_height, video_res_width, webrtc,
    ..Default::default()
})

No behavioral changes—all previous parameters map directly to struct fields.

Original prompt

Pull Request: #1105

Migrate to use the new version of the library so that cargo clippy passes. Preserve all functionality from before upgrading.
