fix: add catch fallback to getRandomItems API query on home page load

[mattsigal]

This prevents slow database scans from timing out and crashing the entire home page loading sequence.

Pull Request

Summary

This PR resolves a critical startup crash on the browse/home page.

During startup, the client queries for random media items to display as the featured background card at the top of the homepage (api.getRandomItems(...)). On slower servers (like home NAS setups) or large databases, this query frequently takes more than 15 seconds to run, exceeding the client-side timeout limit.

Since this call was previously part of the main Promise.all block without a catch fallback, a timeout on the background card query would abort the entire loader promise, causing the homepage to crash and display "No content found" rather than fallback rows.

Changes Made

List the key changes included in this PR.

• Browse.js: Added .catch(() => null) to api.getRandomItems so that slow random backdrop scans do not block or crash the initial loading of critical homepage elements (such as libraries, "Continue Watching", and "Next Up").

• ModernMediaRow.js: Replaced the React component instance ref wrapper check with a native DOM element query (document.querySelector) and added a fallback type check. This resolves the uncaught TypeError: rowNode.contains is not a function crash that was being thrown in the console whenever focus left a row.

Platform
