Refine MPP

[Haakam21]

Summary by cubic

Renamed the MPP integration to MPPX and added a local MppxClient. AgentMailClient now uses the mppx option for fetch and websocket payment credentials.

• Refactors

  • Replaced mpp with mppx across Client, websockets helper, and tests.
  • Added mppx.ts with MppxClient and getPaymentCredentials; removed mpp-types.d.ts and mpp.ts.
  • Moved probe402 into util.ts with wsToHttp; updated mppx and x402 to use it; removed probe402.ts.

• Migration

  • Change AgentMailClient options from { mpp: ... } to { mppx: ... }.
  • Update imports to use wrapper/mppx instead of wrapper/mpp.

^{Written for commit e929ebf. Summary will update on new commits.}
