Add platform credit overview to dashboard

New section below pending purchases/cashouts: one square card per
active platform showing net credit balance, completed purchase count,
and sent cashout count. Loads on page load alongside other dashboard
data. Credits turn yellow below 100 and red at/below 0 with a warning.
Clicking a card jumps to Game Management and opens that platform's
credit modal.
