feat(embeddings): enforce per-request input batch limit (#44574)
* feat(embeddings): add max_batch_inputs pre-call validation

Signed-off-by: Vincent Gimenes <vincent.gimenes@gmail.com>

* add unit tests for max embedding batch size

Signed-off-by: Vincent Gimenes <vincent.gimenes@gmail.com>

* feat(embeddings): enforce batch limit on extra_body input override

Signed-off-by: Vincent Gimenes <vincent.gimenes@gmail.com>

* chore(dashboard): update schema.d.ts for embedding batch size model field

Signed-off-by: Vincent Gimenes <vincent.gimenes@gmail.com>

* fix(embeddings): close Bedrock batch bypass and satisfy ruff PT012

Count max(top-level input, extra_body.input) for batch limits so providers
that ignore extra_body cannot bypass max_embedding_batch_size. Add router
tests and refactor pytest.raises blocks for ruff-tests.

* fix(embeddings): drop unchecked casts in router batch-size check

Signed-off-by: Vincent Gimenes <vincent.gimenes@gmail.com>

* fix(embeddings): route oversized batches to a group deployment that admits them

* fix(embeddings): count extra_body input for any top-level input and prefer admitting deployments before cooldown

* fix(embeddings): log cap rejections to failure callbacks and scope batch routing to embedding calls

* fix(embeddings): apply the batch cap after tag and pre-call filters and fall back on cap rejections

* fix(router): keep embedding cap rejections out of deployment health and hold only for routable cooling deployments

* fix(router): clear the embedding cap rejection mark before a fallback's provider call

A fallback or retry shares the request's logging object, so the mark a rejected attempt set made telemetry skip the fallback deployment's real call. Unit tests now pass a fixed logging start time instead of reading the clock.

* fix(router): log embedding batch rejections once, before a fallback runs

* refactor(router): drop docstrings that restate the code
