fix: escalate to model fallback after rate-limit profile rotation cap (#58707)

* fix: escalate to model fallback after rate-limit profile rotation cap

Per-model rate limits (e.g. Anthropic Sonnet-only quotas) are not
relieved by rotating auth profiles — if all profiles share the same
model quota, cycling between them loops forever without falling back
to the next model in the configured fallbacks chain.

Apply the same rotation-cap pattern introduced for overloaded_error
(#58348) to rate_limit errors:

- Add `rateLimitedProfileRotations` to auth.cooldowns config (default: 1)
- After N profile rotations on a rate_limit error, throw FailoverError
  to trigger cross-provider model fallback
- Add `resolveRateLimitProfileRotationLimit` helper following the same
  pattern as `resolveOverloadProfileRotationLimit`

Fixes #58572

* fix: cap prompt-side rate-limit failover (#58707) (thanks @Forgely3D)

* fix: restore latest-main gates for #58707
