Aptos local CRE minimal: expose Aptos service APIs and harden TXM submission

[cawthorne]

Summary

This PR upstreams the minimal Aptos work needed to run local CRE read-capability flows, while keeping the patch focused and reviewable.

What changed

Relayer Aptos service surface

• Implemented Aptos service support on the relayer:
  • Aptos()
  • AccountAPTBalance
  • LedgerVersion
  • View
  • TransactionByHash
  • AccountTransactions
• Added Aptos type-tag/view payload conversion helpers and transaction conversion helpers.

ChainReader head data support

• Added GetLatestValueWithHeadData for Aptos chainreader.
• Returns head metadata (height + timestamp) from node ledger info after read execution.

Relayer/chain wiring cleanup

• Exposed chain keystore via KeyStore().
• Refactored GetChainInfo() to use shared chain info helper.

Dependency alignment

• Root module updated to a chainlink-common commit on upstream main.

Notes / scope

• This PR is focused on local CRE + Aptos read-path enablement with minimal upstream scope.
• Historical View reads by explicit ledger_version are intentionally not included in this minimal patch and can be reintroduced in a follow-up once dependency stack alignment is complete.

Validation

• go test ./relayer/...
• cd integration-tests && go test ./smoke -run '^TestDoesNotExist$' -count=1 (compile validation)
• Full PR CI
