feat: Admin API enhancements - Create/Update App, Per-App Stripe, One-Time Payments

[HuiNeng6]

Closes #305

Summary

This PR implements the Admin API enhancements requested in issue #305:

1. Create & Update App via Admin API

New Endpoints:

• \POST /v1/admin/apps\ - Create a new app using access token authentication
• \PATCH /v1/admin/apps/:appId\ - Update app properties

Supported update fields:

• \paymentsMode\ - 'test', 'prod', or 'disabled'
• \paymentRequired\ - boolean
• \enableAutomaticTax\ - boolean
• \�llowPromotionCodes\ - boolean
• \ rialPeriodDays\ - number (1-730)
• \ estSubscriptionPlanId\ - string
• \prodSubscriptionPlanId\ - string

2. Independent Stripe per App

New Endpoints:

• \POST /v1/admin/apps/:appId/stripe/connection/:authorizationCode\ - Connect a Stripe account to an app
• \DELETE /v1/admin/apps/:appId/stripe/connection\ - Disconnect Stripe account from an app

Behavior:

• Each app can have its own Stripe Connect account
• Per-app Stripe account takes precedence over admin's default Stripe account
• Existing admin-level Stripe integration remains unchanged for backward compatibility

3. One-Time Payment Support

New WebSocket Action:

• \PurchaseOneTime\ - Create a one-time payment session

Parameters:

• \successUrl\ - Redirect URL after successful payment
• \cancelUrl\ - Redirect URL if payment is cancelled
• \priceId\ - Stripe Price ID for the product

User Data:

• Purchases are stored in \user.purchases\ array
• Each purchase contains: \paymentIntentId, \�mount, \currency, \purchaseDate, \status, \priceId, \productId\

Webhook Support:

• \checkout.session.completed\ (payment mode) - Records purchase in user's data
• \charge.refunded\ - Logs refund events

Testing

All files pass Node.js syntax validation with
ode --check.

Files Changed

• \src/userbase-server/app.js\ - Added Admin API endpoints for app management
• \src/userbase-server/user.js\ - Added one-time payment support and per-app Stripe account support
