fix: add userAgentAppId to Bedrock embedder for code indexing (#10166)

Adds userAgentAppId configuration to the BedrockRuntimeClient in the
code indexing embedder, matching the implementation pattern already
used in the main Bedrock API provider.

This enables proper user agent identification in CloudTrail AWS requests
when using Bedrock for code indexing embeddings.

Fixes #10165
