feat: redesign project pricing export — FOB/DDP basis, variant filename, article column

- Add FOB/DDP basis to export options; DDP multiplies all prices ×1.3
- Rename export file from "pricing" to "{FOB|DDP} {variant}" (e.g. "FOB v1")
- Fix server article missing from CSV summary row (PN вендора column)
- Skip per-row breakdown when neither LOT nor BOM is selected
- Remove empty separator rows between configurations
- Redesign export modal: split into Артикул / Цены / Базис поставки sections

+- `qt_vendor_partnumber_seen` requires INSERT + UPDATE (vendor PN discovery during sync);
+- no DELETE is needed on sync/tracking tables — rows are never removed by the client;
+- `lot` SELECT is required for the connection validation probe in `/setup`;
+- the setup page shows `can_write: true` only when `qt_client_schema_state` INSERT succeeds.
