Description

This PR adds a dismiss action to the outdated build banner, allowing users to temporarily hide the banner during the current app session.

Previously, the banner could only be resolved by updating the app, which meant it would remain visible even when users were already aware of the warning or unable to update immediately. This change introduces a lightweight dismissal mechanism using local Compose state, without altering any existing expiry logic or update behavior.

The banner will reappear on the next app restart if the build is still outdated, ensuring that users continue to receive the reminder while avoiding unnecessary friction within a single session.

Testing

• Verified that the outdated build banner is shown as before when the build is nearing expiry.
• Confirmed that tapping Dismiss hides the banner immediately.
• Confirmed that tapping Update still opens the Play Store or APK download page.
• Verified that the banner reappears after app restart when the build is still outdated.

This change addresses the UX concern described in #14424 while keeping the warning behavior intact.
