Fixes red main. #9144 added a step to the expired-assertion journey in native_media_headers_test that loads a posterless video preview through videoPreviewFrameLoaderProvider. #9138 merged around the same time and replaced native first-frame loading with a static placeholder, removing that provider, so flutter analyze now fails on main with Undefined name 'videoPreviewFrameLoaderProvider'.

Posterless previews no longer fetch anything natively, so the step has nothing left to guard. This deletes it along with its fake video player, restoring the test file to its state before #9144.

Validation

• just mobile-check and just mobile-test pass.

No blockers. The deletion is the right fix for red main.

• The file at this head is byte-identical to its state just before #9144 (blob ad88133c at both fba8a7a9 and ac02ada1), so this is a clean revert of that one step, not a partial edit.
• videoPreviewFrameLoaderProvider no longer exists on main (#9138 removed it). Nothing in mobile/lib still sends native headers for a posterless preview, so no coverage of a live path is lost. The expired-assertion journey still covers freshNativeMediaHeadersProvider, which voice notes use.
• main's one extra commit since this branch (#9118) is relay-only and doesn't touch this file.

Merge gate: Clients / Mobile (Checks) and Clients / Mobile (Android) were still pending when I reviewed. Merge once they're green.
