feat: tooling API set token pool token transfer fees 2.0

[chris-de-leon-cll]

Summary

Adds deployment/tokens.SetTokenTransferFee for v2 token pools (optional min block confirmations, per-destination fee config, merge with on-chain or defaults) via TokenFeeAdapter

Fee Quoter SetTokenTransferFee now uses utils.Optional, Resolve instead of Infer, StripPatchVersion for adapter lookup, and dedupes token addresses per (src, dst) using trimmed strings.

Checklist:

• Add support for partial updates to minBlockConfirmations
• Move test to tokens_and_token_pools_test.go?
  • Keeping it where it is for now - can move it later if needed
• Instead of introducing a new changeset, can we add this to the existing fees adapter?
  • Don't think this is possible at the moment - while both have some similarities, the use case is sufficiently different and may even warrant a new self-serve UI page

Pull request overview

Adds a new token-pool (v2) token transfer fee configuration changeset and updates the existing Fee Quoter fee changeset to use the new utils.Optional + Resolve flow and patch-stripped adapter lookups.

Changes:

• Introduce deployment/tokens.SetTokenTransferFee supporting per-pool min block confirmations and per-destination fee config with merge-from-onchain-or-defaults behavior.
• Add EVM v1_7_0 token adapter + sequences to apply token-pool fee configs and min block confirmations on-chain.
• Update Fee Quoter SetTokenTransferFee to use utils.Optional, Resolve, StripPatchVersion, and trimmed-address deduping; add/adjust integration tests.
