test(perps): add HL abstraction-cycle agentic flows for TAT-3016 validation

- PerpsWithdrawView gets a testID on the available-balance text so
  agentic recipes can read the displayed value and assert the withdraw
  path shows availableBalance, not availableToTradeBalance.
- HyperLiquidProvider.getExchangeClient() is a narrowly-scoped public
  escape hatch used by admin/test flows to drive userSetAbstraction and
  usdClassTransfer via the SDK. Not part of the PerpsProvider interface.
- scripts/perps/agentic: new hl-balance-validation flow captures
  AccountState + perps-market-available-balance-text (PerpsMarketListView)
  + perps-withdraw-available-balance-text (PerpsWithdrawView) with
  deterministic wait_for gates. New hl-provision-fixture flow wraps
  userSetAbstraction / usdClassTransfer so recipes can cycle abstraction
  modes programmatically. New hl-fixture-state eval exposes the balance
  snapshot used by the flow assertions.
- evidence/QA.md + evidence/recipe.json removed from tracking; these are
  per-PR local artifacts and belong under the agentic task dir, not the
  repo.
