Fixes#43057
* fix(auth): clear stale lockout on re-login
Clear stale `auth_permanent` and `billing` disabled state for all
profiles matching the target provider when `openclaw models auth login`
is invoked, so users locked out by expired or revoked OAuth tokens can
recover by re-authenticating instead of waiting for the cooldown timer.
Uses the agent-scoped store (`loadAuthProfileStoreForRuntime`) for
correct multi-agent profile resolution and wraps the housekeeping in
try/catch so corrupt store files never block re-authentication.
Fixes#43057
* test(auth): remove unnecessary non-null assertions
oxlint no-unnecessary-type-assertion: invocationCallOrder[0]
already returns number, not number | undefined.
