Pull request overview

This PR extends Habitica’s server-side payment/analytics pipeline to record subscription renewal events for Stripe and PayPal, and enriches subscription analytics with a “group vs. individual” flag.

Changes:

• Adds a new analytics event type (renewed) and records renewal events from Stripe webhooks and PayPal IPN.
• Extends subscription analytics payload/storage with isGroupSubscription.
• Switches the in-app-purchase dependency to a GitHub-sourced package.
