Summary

• Reverts feat(about): thank license holders by name in the About panel #3923. The About panel goes back to the project links alone: Supporters.json, SupporterList, the "Thanks to these license holders" string and its translations, the tests and the changelog fragment are removed, and AboutPanelCredits returns to AppDelegate+MainMenuActions.swift.
• Naming buyers in the app is dropped, so the opt-in email to buyers was never sent and no name was collected.
• Monetization roadmap task R1.7 is dropped (tablepro-cloud docs/monetization-roadmap.md).

Test plan

• git revert of the squash commit applied without conflicts; nothing outside the reverted files references SupporterList or Supporters.json.
• The project generates and the app builds.
