Commit ee6c0ef904 (Replace sign-in mocked metadata with hardcoded
BackgroundMock) removed the mocked metadata loading path in
MinimalMetadataLoadEffect. Before this change, users with an access
token but an inactive workspace (plan-required state) would get mocked
metadata loaded, which satisfied IsMinimalMetadataReadyEffect's
areObjectsLoaded check. After the change, shouldLoadRealMetadata =
hasAccessTokenPair && isActiveWorkspace is false for plan-required
users, so nothing is loaded, isMinimalMetadataReady stays false, and
MinimalMetadataGater renders the loading skeleton forever instead of the
actual auth modal content.
Fix: Add AppPath.PlanRequired and AppPath.PlanRequiredSuccess to
isOnExcludedPath in MinimalMetadataGater, mirroring how AppPath.Invite
is already excluded — both are pages where the user may have a token but
the workspace isn't fully active, so they don't need metadata to render.
