Proposal: Store Contribution Page ID in the `civicrm_contribution_recur` table

Overview

When a recurring contribution is created with a contribution page. Also store the contribution page ID in the civicrm_contribution_recur table.

This works already for 'normal' contribution.

Example use-case

1. CiviRules can be used when a new Contribution Recur is added and a condition can then be used which Contribution Page this came from.

Current behaviour

Currently for the 'normal' contributions the contribution page ID is stored in the civicrm_contribution table.

Proposed behaviour

1. Add a column to the civicrm_contribution_recur table called contribution_page_id
2. When a contribution recur is added through a Contribution Page then store the contribution page id into this column
3. Optional we can show the data from this field in the user interface when a user views a contribution recur

Workaround

There is a workaround with an extension: https://lab.civicrm.org/extensions/storecontributionpageidoncontribrecur
