Claude API supports up to 32MB PDFs; base64 encoding adds ~33% overhead.
50mb body limit covers the maximum single-document upload case.

The direct `import * as express from 'express'` caused a
MODULE_NOT_FOUND error in the Docker production image since express
is only available as a transitive dependency via @nestjs/platform-express.
Use NestExpressApplication.useBodyParser() which is the official NestJS API.

Two major features in this commit:
1. Streaming Markdown Rendering Optimization
- Replace deprecated flutter_markdown with gpt_markdown (active, AI-optimized)
- Real-time markdown rendering during streaming (was showing raw syntax)
- Solid block cursor (█) instead of AnimationController blink
- 80ms token throttle buffer reducing rebuilds from per-token to ~12.5/sec
- RepaintBoundary isolation for markdown widget repaints
- StreamTextWidget simplified from StatefulWidget to StatelessWidget
2. Multimodal Image Input (camera + gallery + display)
- Flutter: image_picker for gallery/camera, base64 encoding, attachment
preview strip with delete, thumbnails in sent messages
- Data layer: List<String>? → List<Map<String, dynamic>>? for structured
attachment payloads through datasource/repository/usecase
- ChatAttachment model with base64Data, mediaType, fileName
- ChatMessage entity + ChatMessageModel both support attachments field
- Backend DTO, Entity (JSONB), Controller, ConversationContextService
all extended to receive, store, and reconstruct Anthropic image
content blocks in loadContext()
- Claude API engine skips duplicate user message when history already
ends with multimodal content blocks
- NestJS body parser limit raised to 10MB for base64 image payloads
- Android CAMERA permission added to manifest
- Image.memory uses cacheWidth/cacheHeight for memory efficiency
- Max 5 images per message enforced in UI
Data flow:
ImagePicker → base64Encode → ChatAttachment → POST body →
DB (JSONB) → loadContext → Anthropic image content blocks → Claude API

Socket.IO requires its own handshake protocol (EIO=4) which Kong cannot
proxy as a plain WebSocket upgrade, causing 502 Bad Gateway. Switch to
@nestjs/platform-ws (WsAdapter) with manual session room tracking so
Flutter's IOWebSocketChannel can connect directly.
Also add ws/wss protocols to Kong WebSocket routes.
