deprocate getProductPrices query in front end

[anamarn]

TLDR:
Deprecate getProductPrices in the frontEnd and replace it with BillingBaseProductPrices.

In order to test:

• Have the environment variable IS_BILLING_ENABLED set to true and add the other required environment variables for Billing to work
• Do a database reset (to ensure that the new feature flag is properly added and that the billing tables are created)
• Run the command: npx nx run twenty-server:command billing:sync-plans-data (if you don't do that the products and prices will not be present in the database)
• Run the server , the frontend, the worker, and the stripe listen command (stripe listen --forward-to http://localhost:3000/billing/webhooks)
• Buy a subscription for acme workspace the choose your plan should be using the new front end endpoint

logic: Type guard could fail silently if price has unitAmount but not recurringInterval. Consider splitting the type check.

Suggested change

	const baseProductPrices = plans?.plans

	?.baseProduct.prices?.filter(

	): price is NonNullable<typeof price> & {
	recurringInterval: SubscriptionInterval;
	unitAmount: number;
	} => price !== null && 'recurringInterval' in price,
	);
