fix(treasury): attribute warehouse credits per split, page on demand

Three fixes found live, one of them a mislabel on the public page:

- Warehouse credits are attributed by which SPLIT emitted in the credit's
  own transaction, via one immutable-receipt read per warehouse row.
  "Warehouse USDC = Morpheus Subnet" expired the day the /swap fee split
  first distributed — its 2026-06-22 credit ran on the page under the
  wrong product name. Known splits map to products (subnet, swap); a
  bare withdraw or an unmapped split falls to the generic `splits` tag,
  which no longer borrows the subnet's green.
- The pager fetches deeper history when the next-arrow hits the loaded
  edge (Alchemy pageKey cursor via /api/treasury/inflows), with a
  spinner while fetching, a visible failure line that keeps the cursor
  for retry, and a total that stays open-ended ("34+") while a cursor
  remains. Exhausted history and not-yet-fetched are distinct states.
- Known entities carry their real marks: Morpheus logo on receipt-proven
  subnet rows, the red noggles on auction rows, rider cut-outs (via the
  sponsorship card's exported crop) for vault/split rows. Unknown
  senders keep the identicon; no approximated logos.
- Splits links point at explorer.splits.org — app.splits.org answers
  "Account not found" for these SplitV2 contracts (verified in browser).
