Add optional curveType ('eddsa' | 'ecdsa') to the SignMpcRequest body so
EdDSA MPCv2 callers can explicitly distinguish their requests from ECDSA
MPCv2 while reusing the mpcv2round1/2/3 share types. The field is optional
and unconsumed by the handler (dispatch remains coin-derived), keeping
existing ECDSA callers backward compatible.
Ticket: WCI-923
Add optional curveType ('eddsa' | 'ecdsa') to SignMpcV2Round1/2/3Params
in advancedWalletManagerClient.ts. The existing signMPCv2Round1/2/3()
methods already spread ...params into the request body, so the field is
forwarded without any method changes. Existing ECDSA callers are
unaffected because the field is optional.
Ticket: WCI-924
