feat: Overview heatmap improvements (#12359)

This PR adds inbox filtering to the conversation traffic heatmap,
allowing users to analyze patterns for specific inboxes. Additionally,
it also adds a new resolution count heatmap that shows when support
teams are most active in resolving conversations, using a green color to
distinguish it from the blue conversation heatmap.

The PR also reorganizes heatmap components into a cleaner structure with
a shared `BaseHeatmapContainer` that handles common functionality like
date range selection, inbox filtering, and data fetching. This makes it
easy to add new heatmap metrics in the future - just create a wrapper
component specifying the metric type and color scheme.

Unrelated change, the data seeder conversation resolution would not work
correctly, we've fixed it.
