Subject: [PATCH 1/2] fix(tests): replace deprecated Bedrock Claude 3.7 Sonnet
 model ID

AWS Bedrock has reached end-of-life for `claude-3-7-sonnet-20250219-v1:0`,
returning 404s with "This model version has reached the end of its life."
Update test references to `claude-sonnet-4-5-20250929-v1:0` (same capability
surface: thinking, tools, prompt caching, PDF input, vision, computer use).

The bedrock/invoke pass-through tests stay on Sonnet 3.5 since Sonnet 4.5
is converse-only on Bedrock.

Subject: [PATCH 2/2] fix(tests): use Sonnet 4.5 for Bedrock invoke
 prompt-caching tests

Claude 3.5 Sonnet v2 reached EOL on Bedrock 2026-03-01, returning the same
404 EOL error as 3.7 Sonnet. Sonnet 4.5 supports both InvokeModel and
Converse APIs on Bedrock, so use the same model for both routes.
