Test 56 directed Ethereum, Solana, and WIRE swap routes

[joshglogau]

Summary

Adds flow-swap-route-matrix, a serial conformance FlowScenario covering 56 currently advertised directed public-token routes across Ethereum, Solana, and WIRE.

Coverage

• Ethereum ↔ Solana, same-chain distinct-token routes, external-chain → WIRE, and WIRE → external-chain.
• Each route reports authorization, submission, custody where applicable, UWREQ creation, underwriting, lock state, and destination payout as separate Steps.
• LIQETH remains outside the positive catalog while its source-custody policy is unresolved.
• Routes remain serial to avoid shared nonce and balance-baseline races.

Current state

Current master is merged into the branch and the complete TypeScript project-reference compilation passes. The PR remains draft until the full live matrix is exercised and reviewed.

This change does not introduce custom orchestration failure modes, nonce recovery, collateral changes, or private-reserve behavior.

[joshglogau]

Applied the same orchestration/style cleanup in 45b3b06.

The matrix no longer changes shared ClusterBuildPhaseGroup behavior or introduces a failure-mode enum/environment switch. It uses the existing fail-fast model and one public matrix planner.

I also removed the unrelated expansion that had accumulated around the matrix: LIQETH funding/rejection probing, nonce-recovery plumbing, LIQ collateral handling, bigint migrations across existing flows, and their associated tests. Those concerns do not belong in a supported-route conformance PR. LIQETH remains explicitly outside the advertised positive route catalog.

The resulting PR is focused on the 56 supported directed routes, reuses the existing cluster identity/funding/swap/underwriter tools, and is 862 lines smaller in this cleanup commit. Focused route-matrix source typecheck, ESLint, and diff checks pass.
