fix: disable gzip and pad SSE events to prevent proxy buffering

Add gzip off to Nginx import location — the global gzip on was
buffering text/event-stream responses. Pad each SSE event to 4 KB
with comment lines to push past any remaining proxy buffer threshold.

+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.
