Server PR: bitwarden/server#8159
Server SDK Bindings Update PR: bitwarden/sdk-internal#1372
SDK PR which wires up breaking changes: bitwarden/sdk-internal#1363 (⚠️ unmerged)

📔 Objective

The SDK's UserMasterPasswordRegistrationRequest gains a new openOrgInvite field (Option<RegistrationFinishOpenOrgInviteData>) to support finishing registration via an open organization invite link once bitwarden/sdk-internal#1363 merges. Android does not use open-org-invite (that flow is web-only), so this passes null at the production call site and the two matching test expectations to satisfy the new required constructor parameter.

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR adds the new openOrgInvite parameter to the SDK UserMasterPasswordRegistrationRequest construction in AuthSdkSourceImpl.postKeysForUserPasswordRegistration, passing null since the open-org-invite flow is web-only. The two corresponding MockK expectations in AuthSdkSourceTest were updated to match. The null value is consistent with the other web-only registration parameters already passed as null at this call site (orgInviteToken, organizationUserId, providerInviteToken, etc.), so no behavior change is introduced for Android. No security, correctness, or breaking-change concerns were identified in the changed code.

Code Review Details

No blocking findings in the changed code.

Merge readiness note (not a code finding): gradle/libs.versions.toml still pins bitwardenSdk = "3.0.0-8157-eb825d59" and is not modified by this PR, while the description notes the SDK change wiring up this breaking parameter (sdk-internal#1363) is unmerged. All Test CI jobs are currently failing. This PR presumably needs the SDK version bump before it can compile and merge — worth confirming before merging.
