Stats: Fix chartEnd of the forced default range by gates

[dognose24]

This is the follow-up for #96869.

Proposed Changes

• Fix the chart end date when it is determined by the forced 7 days by the feature gate.

Why are these changes being made?

• We need a complete range for all shortcuts.

Testing Instructions

• Spin this change up with Calypso Live branch.
• Navigate to Stats > Traffic page for a Simplte site created after 2024-01-09 with the feature flag: ?flags=stats/new-date-filtering.
• Ensure the default date range is applied to the Last 7 Days and the selected shortcut is the same.
