fix(bedrock): accept Converse messages with no content key (#43936)
* fix(bedrock): accept Converse messages with no content key A user or tool message whose content key is missing (or null, which the message cleanup strips) made every Bedrock Converse request fail with APIConnectionError 'content' before reaching Bedrock. The Converse transform now reads content with .get for those messages, as it already did for assistant messages: a content-less user message adds no block and a content-less tool message becomes a toolResult with empty content. The str branch also sends the continue message text instead of the original whitespace-only text. * fix(bedrock): send the continue message for a content-less user turn * test(bedrock): type the content-less Converse message test parameters * fix(bedrock): accept a Converse system message with no content key * refactor(bedrock): read the system message content with get * test(integration): audit Bedrock Converse messages without content Adds the /audit cells for a chat message whose content key is missing or null on a Converse-routed Bedrock deployment: happy, sad, edge, and chaos rows through the OpenAI SDK, the Anthropic SDK, and raw httpx against the scripted upstream, asserting the caller's response, the body the peer received, and the spend row. The owned-proxy readiness deadline in the integration harness is now INTEGRATION_PROXY_READY_SECONDS (default 70). * test(integration): bound stray spend rows in the mid-burst restart cell --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com>
