ROB-377 Add an MS Teams sink that posts via the Microsoft Graph API - #2192

Conversation
- ms_teams_graph_sink: ROPC sign-in as a service user, posts Adaptive Cards to channels, routes by namespace/subject labels and annotations like Webex/Slack - Shared destination override helper, used by Webex too - MsTeamsMsg renders blocks for both the webhook and Graph senders - Sign-in backoff to avoid Entra ID account lockout - Docs page and unit tests - Ignore tmp/ scratch folder Not yet tested against a real Teams tenant. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
MsTeamsMsg now only builds the adaptive card, so MsTeamsGraphMsg no longer passes an empty webhook_url or inherits a webhook send(). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 150-151: Clarify the fallback behavior in the documentation near
the `send_to_default_if_missing` description: state that the flag applies when
at least one override is configured but neither resolves to a channel, and that
when neither override is configured, the notification goes to the default
`channel_id`.

Summary
ms_teams_graph_sink, an MS Teams sink that posts Adaptive Cards to channels with the Microsoft Graph API. It signs in as a service user (ROPC with delegatedChannelMessage.Send), because Graph doesn't allow posting channel messages with application permissions.namespace_channel_override(namespace labels/annotations), thenchannel_override(subject labels/annotations), then the default channel, or drops the finding whensend_to_default_if_missing: false. An override value can be<channel_id>or<team_id>/<channel_id>.hostedContents, not inline base64. If Teams rejects them, the message is resent without images.core/sinks/common/destination_override.py, shared by Webex and the new sink.MsTeamsMsgonly builds the card now. The webhook POST and the block-to-card loop (write_enrichments) moved out of the webhook sender, so the Graph message can reuse the card rendering.docs/configuration/sinks/ms-teams-graph.rst, covering Entra ID setup, the Teams license step, routing, and a troubleshooting table.Tests performed
