feat(subscriptions): publisher/group-level updates (PR 6/7)

[sarthak688]

PR 6/7 in the Notification SDK stack. Stacked on top of #517.

Adds the two broader-scope subscription writes — publisher-level opt-in/out and topic-group entity scoping.

Methods Added

Layer	Method	Signature
Service	subscriptions.updatePublisher()	updatePublisher(tenantId: string, subscriptions: PublisherSubscriptionUpdate[]): Promise<SubscriptionUpdatePublisherResponse>
Service	subscriptions.updateTopicGroup()	updateTopicGroup(tenantId: string, subscriptions: TopicGroupSubscriptionUpdate[]): Promise<SubscriptionUpdateTopicGroupResponse>

Endpoints Called

Method	HTTP	Endpoint	OAuth Scope
updatePublisher()	POST	notificationservice_/usersubscriptionservice/api/v1/UserSubscription/PublisherSubscription	NotificationService
updateTopicGroup()	POST	notificationservice_/usersubscriptionservice/api/v1/UserSubscription/TopicGroupSubscription	NotificationService

• API spec misspelling preserved: the publisher request body field is publisherID (sic), not publisherId. The SDK's public surface uses the clean spelling; the rename happens at send time inside updatePublisher.
• Both methods accept arrays of entries — callers can batch many publisher/group updates per request.
• updatePublisher supports optional entity scoping (e.g. opt in for two specific folders only); updateTopicGroup always scopes a named topic group to a list of entities.

Example Usage

// Opt out of a publisher entirely
await subscriptions.updatePublisher(tenantId, [
  { publisherId: '<publisherId>', isUserOptIn: false },
]);

// Subscribe a topic group to two folders
await subscriptions.updateTopicGroup(tenantId, [
  {
    publisherId: '<publisherId>',
    topicGroupName: 'JobNotifications',
    entities: [
      { id: '<folderId1>', type: 'Folder', isSubscribed: true },
      { id: '<folderId2>', type: 'Folder', isSubscribed: true },
    ],
  },
]);

Verification

Check	Status
npm run typecheck	✅ clean
npm run lint	✅ 0 warnings, 0 errors
npm run test:unit	✅ 31 tests in notification suite (5 new)

Integration: updatePublisher round-trip — flip the user's opt-in for the first visible publisher, then restore. updateTopicGroup is unit-only because it needs a configured topic group on the test tenant.
