fix(assets): prefer bundled asset over CDN cache when resolving paths

[TheNoumanDev]

Problem

In CDN-provider apps, an asset that is bundled in the app could still be resolved to an on-device CDN-cache file path (e.g. /data/user/0/<app>/files/asset_cache/assets/card_ERE.jpg) instead of its bundle key. That file path is then handed to Image.asset(), which expects a bundle key — so the image renders blank, even though a perfectly good bundled copy ships in the app.

Cause

Utils.getLocalAssetFullPath() (which picks the path to load) checked the CDN cache first, and only fell back to the bundled key:

cdn cache hit? -> /data/.../card_ERE.jpg          (file path)
else           -> ensemble/assets/card_ERE.jpg    (bundle key)

But Utils.isAssetAvailableLocally() (the "do we have it offline?" check) used the opposite order — bundled first, then cache. So the two disagreed: availability said "yes, it's bundled," while resolution returned the cache file path → blank.

Fix

Make the resolver agree with the availability check — bundled first, then CDN cache:

} else if (provider == 'cdn') {
  final assetName = stripQueryParamsFromAsset(asset);
  // Prefer a bundled asset when present: renders instantly, no download.
  if (LocalAssetsService.localAssets.contains(assetName)) {
    return 'ensemble/assets/$assetName';
  }
  // Otherwise use the CDN cache.
  final cachedCdnAsset = CdnAssetCache.instance.getCachedFileIfValid(asset);
  if (cachedCdnAsset != null) return cachedCdnAsset.path;
  return 'ensemble/assets/$assetName';
}

A bundled asset now resolves to its bundle key, so Image.asset reads it directly — no download, and no dependency on the cache path being readable.

What this changes for a project

• Bundled asset (present in the app): now always resolves to the bundle key → renders instantly, offline, on any screen. (Previously could resolve to a cache file path → blank.)
• Not bundled: unchanged — resolves to the CDN cache if cached, otherwise the fallback bundle key.
• Trade-off: if an asset is both bundled and updated on CDN, the bundled copy wins — a CDN update won't override it. Intended: bundled = instant and static.

Out of scope

This PR changes lookup priority only. It does not change how a non-bundled CDN-cached asset renders — that still resolves to a file path and needs a separate *.file loading fix to paint. Deliberately left out of this change.
