Tell users when their organization has moved to Executor v2 - #2269

Summary

When a user finishes importing a v1 organization, Executor v2 writes two keys onto the v1 WorkOS organization's metadata:

• executor_v2_org_slug: the v2 organization slug
• executor_v2_moved_at: an ISO 8601 timestamp

v1 now reads them and tells users of a moved organization where it lives. This is only a notice. The organization keeps working in v1.

Endpoint. GET /api/auth/v2-import now returns { url, moved }. moved is { v2Url, v2Slug, movedAt } | null, and v2Url is <v2 origin>/org/<slug>. The origin is the same one the import link uses (the V2_SIGN_UP_URL origin, validated by parseV2Edge). An organization that has moved is not offered the import again, and its eligibility is not read. moved is null in any of these cases:

• the slug does not match v2's slug rule (^[a-z0-9]+(?:-[a-z0-9]+)*$, at most 45 characters)
• the timestamp is not a full ISO timestamp with an offset
• either key is missing
• the WorkOS read fails
• v1 has no v2 host configured

Notice. It appears on dashboard load when moved is set. It has:

• a "Moved Oct 9, 2026" badge
• the title "<org> now lives in Executor v2"
• a v1 · <name> → v2 · <slug> pair
• the line "Changes made here won't sync to v2."
• "Open <org> in v2" (opens in a new tab) and "Keep using v1"

"Keep using v1" opens a second step: "What went wrong?" with a required free-text field, "Back", and "Send and stay in v1". Send stays disabled until the trimmed text is non-empty.

Snooze. The snooze is stored in localStorage, per browser and per organization:

• ✕, Escape, or "Open in v2": hidden for 7 days
• sending feedback: hidden for 30 days

Sidebar. For a moved organization, the "Move to Executor v2" item becomes "Open in Executor v2" and links to the organization in v2. It stays so the user can still reach v2 after snoozing the notice.

Analytics. These events are added to the typed catalog:

• v2_moved_modal_shown
• v2_moved_open_clicked { via: "modal" | "sidebar" }
• v2_moved_stay_clicked
• v2_moved_feedback_sent { feedback }
• v2_moved_dismissed { step }

The catalog's rules ban user-entered free text and identity properties. This PR adds one narrow, documented exception: feedback the user writes to us and sends on purpose. The organization is attached through the existing PostHog group, so the events have no org_id property.

Tests are in the PR stacked on top.
