feat(provider): support additive provider key lifecycle management

Add `addToLive` parameter to add_provider so callers can opt out of
writing to the live config (e.g. when duplicating an inactive provider).
Add `originalId` parameter to update_provider to support provider key
renames — the old key is removed from live config before the new one
is written.

Frontend: ProviderForm now exposes provider-key input for openclaw app
type, and EditProviderDialog forwards originalId on save. Deep-link
import passes addToLive=true to preserve existing behavior.
