Webhook keys stay at two, and the key list stays short

A tenant can hold two active inbound lead webhook keys, so a CRM can switch to a new key before the old one is revoked. That limit now holds even when two admins generate a key at the same moment: one gets the key, the other is told to revoke one first.

The key list on Admin → Settings → Integrations now shows every active key and the most recent revoked ones — ten rows at most — with a note saying how many older revoked keys are hidden. Revoked keys are kept, so the delivery log still shows which key each attempt used.
