fix: deduplicate remotion to fix useVideoConfig in production

[vzt7]

Problem

The remotion example throws useVideoConfig() error in production:

Error stack trace

installHook.js:1 Error: No video config found. Likely reasons:
-- You are probably calling useVideoConfig() from outside the component passed to <Player />.
   See https://www.remotion.dev/docs/player/examples for how to set up the Player correctly.
-- You have multiple versions of Remotion installed which causes the React context to get lost.

Root Cause

pnpm creates two separate copies of remotion@4.0.418 because peer dependency versions differ between workspace packages:

Package	Resolved remotion peer context
example-remotion	react@19.2.3, react-dom@19.2.3
@json-render/remotion	react@19.2.4, react-dom@19.2.4

Two remotion instances → two React.createContext() calls → <Player /> sets context in one copy, useVideoConfig() reads from the other → "No video config found".

Fix

Add turbopack.resolveAlias in next.config.js to force all remotion imports to resolve from the app's node_modules, ensuring a single instance.

Test plan

• pnpm --filter example-remotion build succeeds with Turbopack
• Verify video generation works in production deployment
