k 6d50357d11 fix: /posts source filter, /performance closed_at basis, funding venue field
- /posts gains an optional ?source= filter. The Macro page was pulling the
  latest-500 posts globally and filtering client-side; rare scanner signals
  (btc_bottom_reversal ~2-4/cycle, funding_reversal hourly) got pushed off the
  page by frequent Trump posts, so Macro falsely showed "no signals".
- /performance now filters and orders by closed_at (realized-PnL-in-window)
  instead of opened_at, so it shares ONE basis with the frontend Analytics
  page (which filters every window by closed_at). Boundary trades no longer
  land in one basis but not the other.
- funding snapshot returns the actual `venue` (provider.name) so the frontend
  label follows the real data source instead of hardcoding "Binance".

72 tests pass.
