fix: Macro fetches by source, Analytics single-basis stats, funding venue label

- Macro page fetches getPosts(200, 1, source) per active tab instead of
  filtering the latest-500 global feed — rare bottom/funding signals no longer
  vanish behind Trump posts (backend now supports ?source=).
- Analytics: compute ALL time windows from the one closed_at-filtered trades
  list; dropped the 30d-only backend /performance special-case that mixed an
  opened_at basis into the same screen as the closed_at metric grid. Trade
  fetch raised 100→500 so the local computation covers ample history.
- Funding panel shows snap.venue (capitalized) instead of hardcoded "Binance".
- lib/api: getPosts gains optional source param; FundingSnapshot gains venue.

tsc + next build clean.
