[Products] Extract subscriptions outside of the Product DB table - Part 2

[hichamboushaba]

Closes: #12752

Description

This PR builds on top of what was added in #12766, it adds the saving logic, it updates both addProduct and updateProduct functions to handle passing the changed subscription details too.

Steps to reproduce

1. Open the app.
2. Navigate to the Products tab.
3. For some scenarios: open an existing subscription product
4. For other scenarios: create a new subscription product

Testing information

• Confirm that saving changes of an existing product works as expected.
• Confirm that creating a new subscription product works.
• Confirm that duplicating a subscription product duplicates all subscription details.
