Fix Opus 4.6 thinking blocks, re-add Amazon Nova models

Browse source 
- Opus 4.6 returns multiple content blocks (thinking + text); was only
  reading content[0] which was the thinking block (just '{')
- Now iterates all blocks and extracts only type:'text' blocks
- Added debug logging for Bedrock response structure
- Re-added Nova Pro, Nova Lite, Nova Micro with correct region metadata
