feat: price_quality в конфигураторе; фикс пустого lot_description в экспорте цен

price_quality теперь синхронизируется не только в прайслист, но и в
LocalComponent/services.ComponentView (/api/components) — виден в
выпадающем списке поиска (цветная точка), в таблице конфигуратора
(левая колонка-пиктограмма) и на вкладке «Ценообразование» (подсветка
строки). Цветовая шкала вынесена в один модуль web/static/price-quality.js
(подключён в base.html), чтобы не дублировать расчёт цвета по шаблонам.
Шкала — градиент 0 (красный) → 5 (жёлтый) → 9 (зелёный).

Экспорт цен (internal/services/export.go): resolveLotDescriptions был
заглушкой, всегда возвращавшей пустую карту — строки BOM/не-BOM в
экспорте всегда оставались без описания LOT. Заменён на реальный
запрос к local_pricelist_items текущего выбранного прайслиста
(LocalDB.GetLocalDescriptionsForLots), по аналогии с уже существующим
GetLocalLotCategoriesByServerPricelistID.

+- `local_pricelist_items.lot_description` is the single source of a LOT's description at runtime (populated by sync from `qt_pricelist_items.lot_description`); do not join the legacy `lot` table for it. Every read path resolves it through the currently selected pricelist (active estimate, or the configuration's own `PricelistID` where applicable) — see `LocalDB.GetLocalComponent`/`ListComponents` (component views, quote line descriptions) and `LocalDB.GetLocalDescriptionsForLots` (export pricing rows in `internal/services/export.go`). Do not add a second description source (e.g. `VendorSpecItem.Description` from BOM import is a distinct, separate field — it's only ever used as a display fallback in front of the LOT description, never merged back into it);
 - configuration `items` and `vendor_spec` are stored as JSON payloads inside configuration rows;
 - `local_components` table has been removed; any reference to it is dead code.

+`price_quality` is synced through `LocalPricelistItem` (pricelist detail page) and, separately, through `LocalComponent`/`services.ComponentView` (`/api/components`, used by the configurator's search dropdown and item table) — both read paths go through `pricelistItemRow`/`toLocalComponent()` in `internal/localdb/components.go`, still scoped to the currently selected pricelist. The color scale (red 0 → yellow 5 → green 9, gradient) lives in **one shared JS module**, `web/static/price-quality.js` (loaded by `base.html` for every page) — `priceQualityColor`/`qualityDotHtml`/`qualityBadgeHtml`/`qualityRowStyle`. Do not reimplement the color scale locally in a template; add a new helper to that module instead. Used in: pricelist detail "Качество" column, configurator search dropdown (colored dot), configurator table (leftmost quality-dot column), pricing tab (row background tint).
 
 The real table also has `price_method`, `price_period_days`, `price_coefficient`, `manual_price`, `meta_prices` and `lead_time_weeks` columns, owned and written by the external pricing engine that maintains `qt_pricelist_items` — **keep them in the table for backward compatibility with that system; QF must never drop, rename, or write to them.** QF itself does not model, sync, or display any of them (tried once, removed as unused/dead in the client). Do not re-add them to `models.PricelistItem`/`LocalPricelistItem` without a concrete UI need.
