Clearer analytics: where members come from, where points go

A sharper Analytics tab, plus a quiet points-expiry fix worth knowing about:

• See where new members actually come from — the Analytics tab now breaks down enrollments by source, so you can tell how many members joined at checkout, from the loyalty landing page, via import, or another entry point — instead of one combined total.
• Earning sources now have real names — points awarded through Shopify Flow or an order edit used to show up as raw internal labels. They now show the actual rule or action name, so the earning breakdown reads the way you'd expect.
• Member growth chart, cleaned up — the chart no longer shows a false spike from members whose join date was backfilled during a data import, and a short caption now explains the chart's fixed time window.
• Fixes — points expiry now always counts from a customer's most recent activity rather than their oldest purchase, so the countdown (and the expiry-warning email) reflects true inactivity instead of understating how much time is left.
