Akshat Shah 5f29454ab7 feat(router): yield session-affinity pin when pinned deployment is saturated
Adds an opt-in router setting, session_affinity_yield_on_saturated_deployment.
When a session is pinned to a deployment that is at its max_parallel_requests
limit and another deployment in the model group has capacity, the turn routes
to the idle deployment instead of queueing or 429ing behind the pin. When
every deployment is full the filter keeps today's behavior. The pin itself is
kept so the session returns to its warm deployment once it frees up.

Fixes #45868
