Replace deprecated model IDs with -latest aliases

The hardcoded Claude 3 model IDs (claude-3-haiku-20240307, claude-3-sonnet-20240229)
are deprecated and broken. Replace them with -latest aliases (e.g., claude-haiku-4-5-latest)
so the tutorials automatically use the newest model version without code changes.

Changes:
- Update MODEL_NAME in all 3 variants (Anthropic 1P, Bedrock/anthropic, Bedrock/boto3)
- Update tool use notebooks from Sonnet 3 to claude-sonnet-4-5-latest
- Update eval notebooks from Haiku 3 to claude-haiku-4-5-latest
- Update markdown prose to reference "Claude Haiku (latest)" instead of "Claude 3 Haiku"
- Unpin SDK versions in AmazonBedrock/requirements.txt for alias support
