feat: Add comprehensive Amazon Bedrock integration support

Add complete Amazon Bedrock integration to Claude Relay Service with:

## Core Features
- ✅ Bedrock account management with encrypted AWS credential storage
- ✅ Full request routing to AWS Bedrock with streaming support
- ✅ Integration with unified Claude scheduler system
- ✅ Support for Inference Profiles and Application Inference Profiles
- ✅ Configurable default and small-fast model settings

## Backend Services
- Add bedrockAccountService.js for account management
- Add bedrockRelayService.js for request forwarding
- Integrate Bedrock accounts into unifiedClaudeScheduler.js
- Update admin and API routes to support Bedrock endpoints
- Add comprehensive configuration options to config.example.js

## Frontend Integration
- Complete Vue.js Web UI for Bedrock account management
- Account creation form with AWS credentials and model configuration
- Real-time account status monitoring and statistics
- Edit/update capabilities for existing accounts

## CLI Support
- Interactive CLI commands for Bedrock account operations
- Account creation, listing, updating, and testing
- Status monitoring and connection validation

## Security & Performance
- AES encrypted storage of AWS credentials in Redis
- Support for temporary credentials (session tokens)
- Region-specific configuration support
- Rate limiting and error handling

This integration enables the relay service to support three AI platforms:
1. Claude (OAuth) - Original Claude.ai integration
2. Gemini - Google AI integration
3. Amazon Bedrock - New AWS Bedrock integration
