Replaces the simple cancel-subscription confirmation dialog with the Churnkey-hosted cancel flow when the churnkey_cancellation_enabled feature flag is on, so we can collect survey data and run cancellation A/B tests through the Churnkey dashboard. - Vite plugin (cloud-only) injects the Churnkey embed loader using VITE_CHURNKEY_APP_ID; non-cloud builds and missing env var no-op. - useChurnkey composable wraps window.churnkey.init; launcher fetches HMAC credentials from /api/billing/churnkey/auth and delegates cancellation to the existing /api/billing/subscription/cancel via handleCancel so the backend stays the source of truth. - Feature-flag gating via useFeatureFlags + remoteConfig falls back to the legacy dialog whenever the flag is off, Churnkey is unconfigured, or the embed script fails to load. - New PostHog events: cancellation_flow_opened, cancellation_flow_closed (with outcome), and cancellation_reconsidered (sets a user-level property for downstream cohort analysis).
