Add option to sort by date in the timeline screen

[reshmabidikar]

The Timeline screen currently groups entries by object type (Invoices, Payments, etc.) rather than displaying them in chronological order.

While this organization is useful in some cases, it makes it difficult to visually follow the actual sequence of events. For example, payments that occurred before certain invoices are displayed only after all invoices because they belong to a different object type.

Proposed Change

Add a Sort by Date option to the Timeline view.

Default behavior: Keep the existing grouping by object type to preserve the current user experience.
Sort by Date: When selected, display all timeline entries in chronological order, regardless of object type.

This would allow users to easily inspect the true order in which events occurred while maintaining the existing view as the default.

An option added:

Based on an internal discussion, we need to:

1. Change the default ordering to be date first, type second with well defined ordered list of types - i.e. START_BILLING comes before STOP_BILLING even for same exact date.
2. Remove the new "GROUP BY" drop-down.

Tested with Kaui 4.0.26-be27c98 .

1. The STOP_BILLING/STOP_ENTITLEMENT events come before the START__BILLING/START_ENTITLEMENT:

2. For the same date, the STOP_BILLING/STOP_ENTITLEMENT should be shown one after the other. In the screenshot below, the BLOCKING_STATE event is shown between them:
