feat(bedrock): apply bedrock_request_metadata_fields on the /bedrock pass-through routes (#47040)
* feat(bedrock): apply bedrock_request_metadata_fields on the /bedrock pass-through routes

* fix(bedrock): move Invoke body requestMetadata into the signed header and match Bedrock's ASCII whitespace rule

* fix(bedrock): keep Invoke body requestMetadata in the body and answer bad metadata as AWS does

Invoke requests whose body already carries requestMetadata keep the resolved pairs in the body
instead of the 8,500-character signed header. Malformed caller metadata now answers 400 with the
ValidationException error type the AWS SDK expects, and drop_params drops bad pairs on both the
pass-through routes and /v1/chat/completions. The caller-pair dedupe is linear, and the chat
validator treats \s as ASCII whitespace, as Bedrock does

* fix(bedrock): match Bedrock's 400s and header limit on pass-through request metadata

Invoke metadata too long for the 8,500-character header now goes in the body,
Invoke requestMetadata null answers 400 like Bedrock, Converse type errors carry
SerializationException, violation messages name the failing key, and the reserved
user_api_key_ prefix is matched case-insensitively after trimming whitespace

* fix(bedrock): trim the Invoke metadata header to Bedrock's limit and drop bad requestMetadata under drop_params without the setting

* fix(bedrock): leave /bedrock pass-through bodies as sent when request metadata forwarding is off

Global drop_params no longer rewrites requestMetadata on the pass-through routes unless
bedrock_request_metadata_fields is set. Chat keeps dropping bad pairs under drop_params.
Adds a tests/integration wire test for the four pass-through actions and removes an unused
parameter from the Invoke header helper.

* test(bedrock): drive the pass-through metadata wire test with boto3's bearer key env var

* fix(bedrock): trim the pass-through invoke metadata header and stop Nova invoke from checking metadata it drops

* test(bedrock): cover pass-through metadata header trimming, malformed caller metadata, and chat drop_params on the wire

* fix(bedrock): match requestMetadata keys and values against the whole string so a trailing newline cannot pass the 256-character limit
