Subject: [PATCH 2/2] fix: cache Team Dashboard data to avoid slow load on
 every open

Add `lastDashboardData` cache property so that when the Team Dashboard
panel is opened after the first load, cached data is sent to the webview
immediately instead of waiting for a full backend fetch + maturity score
calculation. Fresh data is still fetched in the background and replaces
the cached view when ready. The cache is cleared alongside other stat
caches when the user explicitly clears the session cache.
