P1 Badge Use versioned Bedrock model IDs for Sonnet 4.6

The new Bedrock entries use anthropic.claude-sonnet-4-6 / us.anthropic.claude-sonnet-4-6, but every other Anthropic Bedrock ID in this table is versioned (for example ...-v1:0 immediately below), and the Bedrock client forwards the selected model string directly as modelId (packages/proxy/src/providers/bedrock.ts). In environments using Bedrock secrets, this makes the newly added Sonnet 4.6 model selection fail with an unknown/invalid model ID instead of invoking Anthropic Sonnet 4.6.
