pdf-parse@2.4.5 pulls in @napi-rs/canvas (native Skia binary) which
crashes on import in Alpine containers. Moved to lazy require() so the
app starts normally and pdf-parse loads only when PDF conversion is
actually requested.
- Lazy-load pdf-parse in pdfToStatement to avoid startup crash
- Add libc6-compat, fontconfig, freetype to Alpine runner stage
- Increase npm fetch timeouts in both Dockerfiles for slow networks
- Add connectionTimeoutMillis to pg Pool for faster failure detection
- Добавлена переменная LLM_MODEL в конфиг
- Увеличен max_tokens до 32768 для крупных выписок
- Включен response_format: json_object
- Добавлен скрипт test:llm для проверки подключения к LLM-серверу
