feat: Add date range filtering to mood status view

Enhances `StatusListView` to support filtering based on
a date range by adding 'from' and 'to' query parameters.
This enables users to view status updates within a specified
date range, improving data accessibility.

Implements click event on calendar heatmap to redirect to
filtered mood page, supporting targeted data exploration.
