Add Slack revenue notifications to Stripe webhook (invoice.payment_succeeded)

[Copilot]

This updates the Stripe webhook flow so confirmed invoice payments are surfaced in Slack in real time, using server-side signature validation and environment-scoped secrets. The webhook now emits structured payment notifications only for invoice.payment_succeeded events.

• Webhook event handling

  • Extends /api/webhook to process invoice.payment_succeeded (instead of a no-op path).
  • Extracts amount_paid, currency, and invoice description from the Stripe payload.
  • Adds defensive amount parsing to avoid runtime failures on malformed values.

• Slack integration (server-mediated)

  • Adds notify_slack(amount, currency, message) in api/index.py.
  • Sends a structured Slack Incoming Webhook payload (status, amount, description).
  • Skips delivery if SLACK_WEBHOOK_URL is unset and handles request failures safely.

• Runtime configuration and secrets

  • Reads and applies STRIPE_SECRET_KEY, STRIPE_ENDPOINT_SECRET, and SLACK_WEBHOOK_URL from environment variables.
  • Keeps credentials out of source while preserving strict Stripe signature verification.

if event_type == "invoice.payment_succeeded":
    invoice = event.get("data", {}).get("object", {})
    amount_paid = int(invoice.get("amount_paid") or 0)
    currency = str(invoice.get("currency", "")).upper()
    description = str(invoice.get("description") or "Pago de cliente confirmado")
    notify_slack(amount_paid / 100, currency, description)

Pull request overview

This PR extends the existing Flask /api/webhook Stripe webhook handler to emit a Slack Incoming Webhook notification when an invoice.payment_succeeded event is received, and adds unit tests to validate the behavior and error handling.

Changes:

• Handle invoice.payment_succeeded in /api/webhook by extracting amount_paid, currency, and description, then calling a Slack notifier.
• Add notify_slack(amount, currency, message) to send a structured Slack webhook payload (and no-op when SLACK_WEBHOOK_URL is unset).
• Add tests/test_stripe_webhook.py to cover Slack-notification behavior, ignored event types, and invalid payload handling.
