Mathias Beaulieu-Duncan 4446288bb6 feat(altcha): add Svrnty.CQRS.Altcha.Grpc with default verifier + proto
The default transport for IAltchaVerifier / IAltchaChallengeProvider —
calls a self-hosted altcha service over gRPC.

Wire contract
- Protos/altcha.proto defines svrnty.cqrs.altcha.v1.AltchaService with
  CreateChallenge + VerifyChallenge RPCs. Shipped in this package as
  source-of-truth; Go (and other) implementations vendor a copy.
- Challenge.challenge_hash is named (not "challenge") to avoid a C#
  property/class name collision; the MinimalApi widget JSON remaps.

Runtime
- AltchaGrpcVerifier maps RpcException → AltchaVerifyResult.Fail with
  a diagnostic reason ("verify-timeout", "service-unavailable", etc.)
  so the auth check surfaces a clean Unauthorized without leaking
  transport detail.
- AltchaGrpcChallengeProvider lets create-challenge failures bubble
  (challenge endpoint should 5xx if altcha is down — clients retry).
- AltchaGrpcOptions.TokenProvider hook for consumer-supplied HMAC
  service-token minting (plan-b will plug in ServiceTokenIssuer).
- AddGrpcClient<AltchaServiceClient> registered with HttpClientFactory.

AddSvrntyAltchaGrpcVerifier(Action<...>) and overload binding from
IConfiguration cover both wiring styles.
