feat: adds PDF import with conversion to JSON 1.0

- Accept only PDF and JSON files in import modal and API - Convert PDF statements to JSON 1.0 via LLM (OpenAI-compatible) - Use multipart/form-data for file upload (multer, 15 MB limit) - Add LLM_API_KEY and LLM_API_BASE_URL for configurable LLM endpoint - Update ImportModal to validate type and send FormData - Add postFormData to API client for file upload

+## Правила конвертации
+
+1. Суммы — всегда в копейках (рубли × 100). Пример: 500,00 ₽ → 50000, -1234,56 ₽ → -123456.
+2. amountSigned: приход — положительное, расход — отрицательное.
+3. operationAt — дата и время, если не указано — 00:00:00, offset +03:00 для МСК.
+4. commission — если не указана — 0.
+5. description — полный текст операции как в выписке.
+6. accountNumber — только цифры, без пробелов и дефисов.
+7. openingBalance / closingBalance — в копейках.
+8. bank — краткое название (VTB, Sberbank, Тинькофф).
+9. exportedAt — дата формирования выписки.
+10. transactions — хронологический порядок.
+
+## Требования
+
+- transactions не должен быть пустым.
+- Все числа — целые.
+- Даты — ISO 8601 с offset.
+- currency всегда "RUB".
+- schemaVersion всегда "1.0".`;
