Disconnecting a sync provider now calls the provider's revoke endpoint
(DELETE /v1/permissions for Wahoo) before dropping the local row, so
tokens don't accumulate against Wahoo's per-(app,user) cap. The token
exchange now classifies Wahoo's "Too many unrevoked access tokens" 400
as a distinct OAuthError code, and the connections settings page shows
a localized banner for that and other connect failures instead of a
silent ?error=sync_failed.
