Changes

Bedrock AI Integration

• Integrated Amazon Bedrock for AI chat responses using the Titan Text G1 Lite model
• Implemented chat context management to maintain conversation history
• Created session-based conversation handling with automatic cleanup
• Added test environment detection for smooth CI/CD process

Chat UI Improvements

• Fixed content text visibility issue where messages were being cut off under the input area
• Converted fixed pixel measurements to relative units (rem) for better responsiveness
• Implemented proper padding and scroll behavior throughout chat interfaces
• Added bottom spacing gradient for better visual transition

Internationalization

• Added missing translation keys for AI Assistant components
• Added chat page title translations in English, Spanish and French
• Added input placeholder translations in all supported languages

Testing Improvements

• Created comprehensive mocks for AWS services
• Implemented test-friendly version of the Bedrock service
• Updated test files to properly mock chat functionality

Does this PR introduce a breaking change?

No. This implementation maintains backward compatibility with existing components while adding new functionality.

What needs to be documented?

• AWS Cognito Identity Pool setup required for Bedrock access
• IAM permissions required for Bedrock model access
• Environment variables for AWS configuration

Technical Details

AWS Configuration Required

To use this feature, you'll need:

1. Cognito Identity Pool (not just User Pool)
2. IAM role with permissions for bedrock:InvokeModel
3. Configuration of the Identity Pool to use the IAM role
