Adds the newly introduced batching to the SkyBrowser topic updates

[Copilot]

Pull request overview

This PR integrates the shared Batcher utility into the SkyBrowser topic subscription flow, updating the SkyBrowser reducer to accept partial/batched updates and reduce Redux dispatch frequency.

Changes:

• Batch incoming skybrowser topic messages via Batcher before dispatching updateSkyBrowser.
• Update updateSkyBrowser reducer to accept Partial<SkyBrowserUpdate> and apply field-level updates.
• Adjust derived SkyBrowser state updates to be conditional on receiving browsers data.

updateSkyBrowser now accepts Partial<SkyBrowserUpdate>, but the reducer still resets the entire SkyBrowser state whenever payload.browsers is missing (because the if (action.payload.browsers && ...) falls through to the reset else). With batching/partial updates this can cause the UI to clear on updates that only include selectedBrowserId/cameraInSolarSystem. Adjust the logic so that the reset/validation only happens when payload.browsers is present, and when payload.selectedBrowserId is present without browsers validate it against the existing state.browsers (reset only if the id is invalid).

Lol realised now that I'm basically reiterating what Copilot already found 🤷‍♂️
