I'm building a blog feature in Next.js 16. Could you write a server-side action file to process new post form submissions? I need a handler that processes form inputs for post title and content, validates the fields before saving to the database, revalidates the cache for the posts route, and handles validation errors gracefully. Please provide the full TypeScript code file.
