fix(bedrock): correct Opus 4.7 model ID and add adaptive thinking support

Browse source 
- Rename model ID from "anthropic.claude-opus-4-7-v1" to "anthropic.claude-opus-4-7"
  to match the correct Bedrock model identifier (per PR #12288)
- Update BedrockAdditionalModelFields to support adaptive thinking type
- Add BEDROCK_ADAPTIVE_THINKING_ONLY_MODEL_IDS for Opus 4.7
- Opus 4.7 uses thinking.type: "adaptive" with output_config.effort
  instead of "enabled" with budget_tokens (which returns 400 error)
