Description
Problem:
In the current versions of Foreman/Katello (up to Foreman 3.15 and see also Red Hat Satellite 6.17), the RPM package details page in the Web UI does not provide a changelog tab. This makes it difficult for administrators to review package history and understand the context of updates without leaving the interface.

Why this matters:

Security & compliance: Changelogs often include CVE references and bug fixes, which are essential for audits.

Operational efficiency: Saves time by avoiding the need to manually run rpm -q --changelog or check external changelog sources.

Transparency: Improves visibility into what an update changes before applying it in production.

Proposed solution:

Add a new “Changelog” tab alongside the existing “Details” and “Dependencies” tabs on the RPM package details page.

Pull changelog metadata from the RPMs already synced by Pulp/Katello.

Display changelog entries in a user-friendly format (optionally collapsible for long histories).

Environment observed:

Red Hat Satellite 6.17

Foreman/Katello up to version 3.15

Impact:
This feature would significantly improve the administrator experience by bringing critical package update information directly into the Foreman/Katello UI.
