* feat(subscriptions): detect Microsoft Teams webhook URLs and emit Adaptive Cards Status-page webhook subscribers receive channel-native payloads for Slack and Discord URLs; any other URL - including Teams Workflows and the legacy Office connector - gets the generic JSON body, which Teams cannot render as a card (issue #1156). This adds a `teams` flavor: - `detectWebhookFlavor` recognizes hostnames ending in `.logic.azure.com`, `.powerplatform.com`, or `.webhook.office.com` (parsed, not substring, so a path like `?to=webhook.office.com` stays generic). - `buildTeamsPayload` emits an Adaptive Card 1.5 inside the `application/vnd.microsoft.card.adaptive` message envelope, mirroring the ms-teams monitor-alert provider's wire format. The card has a status-colored header container (attention/warning/good/accent), a FactSet with status/page /timestamp, the update message, affected components, manage/unsubscribe links, and a "View details" action. - `buildTestPayload('teams')` emits the matching test card. - Dashboard: `FLAVOR_LABELS` gets a "Microsoft Teams" entry so the subscribers table shows the right badge; the subscriber form's helper text now names Teams alongside Slack and Discord. - Docs: a Microsoft Teams section lives between Discord and Generic in the subscriber reference. Tests mirror the Slack/Discord coverage: four flavor-detection cases (plus a negative substring case and a malformed-URL fallback), three send-notification cases (envelope shape, manage/unsubscribe links, maintenance deep link), and one `buildTestPayload` case. All 54 webhook test steps pass under `deno test --no-check`. Closes part of #1156.
