System updates

Improved plan downgrade behavior.
When switching to a lower-tier plan:
Templates that exceed the new plan’s limits are deactivated (the last added ones are disabled, the earlier ones remain active). They are not automatically reactivated when upgrading back to a higher-tier plan.
Geopushes that exceed the new plan’s limits are disabled. They are not automatically re-enabled when upgrading.
Managers are blocked. They are not automatically unblocked when upgrading.
API access is closed. It will automatically resume upon returning to a higher-tier plan (Grow or above).
Stripe / PayPal and other third-party services are disabled, except for SMS/email messengers — those remain available to all plans. Payment systems will not be automatically reactivated upon upgrade.
The referral program is disabled. It will automatically resume upon upgrade.
Autopush notifications are disabled on the Grow plan and below.
Fixed incorrect point expiration logic (sometimes more points expired than intended).
Fixed incorrect behavior when canceling a membership subscription — it now deactivates only after the paid period ends.
Fixed the sender name in upcoming payment notifications for agencies. It now correctly displays "Boomerangme" instead of the agency’s name.
Added a new filter for the client database. You can now filter clients by the bonus balance on their reward card — filter name: "Card bonus balance".
Added the ability to integrate Boomerangme with WooCommerce — https://docs.boomerangme.cards/wordpress-woocommerce.
