Fix clipboard crash: use SetDataObject(false) to skip Flush()

Read lastActiveOrg cookie in both the browser JS path and HttpClient

Add Settings → Diagnostics panel showing app state, last request
details, cookie store counts/domains, and stored cookie names.

-## What's new in beta.36
+## What's new in beta.49
+
+### Architecture
+- All data (usage, plan, overage, prepaid credits) now fetched via the persistent background WebView2 — the same always-live session as the macOS app, so Cloudflare cookies never expire between refreshes
+- HttpClient path kept only as a brief startup fallback before the browser is ready
+- Settings file simplified: only stores session signal, burn history, and user preferences — no more cached API responses
 
 ### Bug fixes
-- Settings no longer incorrectly shows "Not signed in" when limits are working
-- Session Diary now shows correctly after the first successful refresh
-- Extra Usage Credits section now restored from cache on startup
-- Plan name, overage, and prepaid credits are now cached and shown immediately on launch
-- App now loads cached state instantly on startup before the background refresh completes
+- Plan label (e.g. "Pro") now updates on every refresh, not just at login
+- Extra Usage Credits values now correct (were 100× too large)
+- Limit and balance now update live on every refresh
+- Refresh interval dropdown now shows "1 min", "2 min" etc. correctly
+- ComboBox no longer flashes bright blue when clicked
+- Buttons now show a visible pressed state
+- Footer "Updated X ago" counter now ticks every second; shows "X min, Y sec ago" past 60 s
+- Removed stray sparkline bars from the 5 h and 7 d limit cards
+- App window now shown on launch
+
+### UI improvements
+- Gauge percentage larger, "used" label removed
+- Each limit card now shows an "after reset" or "today HH:MM" badge
+- Session Diary card redesigned to match macOS layout (stats row + sparkline, no Claude header)
+- Reset date moved inline with time remaining
