Updated date picker style and usability

There has been a small update to the style and usability of the date picker on some of the newer pages in PMI.

The main change is for dates where the user can select a range of multiple days or multiple months. There was previously a calendar selection box for both the start date and the end date of the range. The update replaces the two calendar boxes with a single calendar box where the user can click twice to select their range of dates. This is common date picker functionality.

This update does not affect all pages in PMI. Older pages will get the new style date picker in future upgrades. The affected pages are:

GM daily digest

GoGreen cockpit

Planning setup (GoGreen)

KPI targets (including Goal distribution tool)

Live forecast (new view in pilot only)

Advanced settings pages: Period locking, Fact sheets, Operational status

Import status

User administration
