fix(ci): restore changed-path detection on multi-commit pushes

Push-чекаут в quality-воркфлоу делался с fetch-depth: 2, поэтому BEFORE_SHA (github.event.before) при пуше нескольких коммитов отсутствовал в чекауте, и git diff падал с "fatal: bad object" (exit 128). Чекаут переведён на fetch-depth: 0; перед диффом добавлен guard git cat-file -e: если before недоступен (force-push), шаг не падает, а уходит в полный прогон через empty-diff fallback.
fix(web): add horizontal inset to frame section content

Denozordec	f861d0fa8c	fix(ci): restore changed-path detection on multi-commit pushes quality / commitlint (push) Skipped Details quality / changes (push) Successful in 7s Details quality / docker-check (push) Skipped Details quality / openapi (push) Successful in 26s Details quality / web (push) Successful in 1m6s Details quality / go (push) Successful in 55s Details quality / bird2 (push) Successful in 16s Details CD / quality (push) Successful in 2m59s Details CD / publish (push) Successful in 5m17s Details Push-чекаут в quality-воркфлоу делался с fetch-depth: 2, поэтому BEFORE_SHA (github.event.before) при пуше нескольких коммитов отсутствовал в чекауте, и git diff падал с "fatal: bad object" (exit 128). Чекаут переведён на fetch-depth: 0; перед диффом добавлен guard git cat-file -e: если before недоступен (force-push), шаг не падает, а уходит в полный прогон через empty-diff fallback.	2026-09-25 23:54:48 +07:00
Denozordec	2f914bcc65	fix(web): add horizontal inset to frame section content quality / commitlint (push) Skipped Details quality / changes (push) Failing after 8s Details quality / openapi (push) Skipped Details quality / web (push) Skipped Details quality / go (push) Skipped Details CD / quality (push) Failing after 11s Details quality / bird2 (push) Skipped Details quality / docker-check (push) Skipped Details CD / publish (push) Skipped Details Контент карточки «Сравнение ревизий» и шела аналитических карточек прилипал к рамке FramePanel: в contentClassName передавался только вертикальный py-, а FrameSection рендерит панель с p-0. Добавлен px-5 — горизонтальная вставка по константе кита panelCardInsetClassName, на одной оси с остальными карточками (мониторинг, дашборд).	2026-09-25 22:54:47 +07:00
Denozordec	7a10138990	fix(web): open select popups below trigger instead of over it Селекты приложения использовали alignItemWithTrigger по умолчанию: Base UI накладывает выбранный пункт списка на триггер, а у селектов с плейсхолдером (без значения, например «Ревизия A/B» на странице операций) попап целиком накрывал триггер — выглядел как сломанный список вместо выпадающего меню. В обёртке SelectMenu/SelectField выставлен alignItemWithTrigger=false — список раскрывается под триггером у всех селектов приложения, как это делает и вендорский data-grid-pagination.	2026-09-25 22:34:04 +07:00
Denozordec	391f34a53d	chore: keep staged-context.ps1 array on single staged file Пайплайн Sort-Object разворачивал одноэлементный массив в скаляр, из-за чего под StrictMode падал доступ к .Count и скрипт возвращал exit 1 при ровно одном застейдженном файле. Обёртка @() сохраняет массив; сообщения коммитов по одному файлу снова проходят обязательную проверку.	2026-09-25 22:33:32 +07:00
Denozordec	ecd48642de	fix(web): align grid columns with reui reference and clean labels Гриды операций и расписания выровнены по эталону data-grid-filtering-2: явные размеры колонок (size в columnDef) вместо равномерного деления при table-layout: fixed — колонка названия доминирует, второстепенные сжаты по содержимому, пропали обрезанные имена («partner-dom…», «Обновлен...»). Убраны фейковые многоточия из JS-срезов: ID ревизии и варианты выбора в сравнении теперь показываются целиком, а усечение делает CSS-truncate. Подписи «Ревизия A/B» переведены на Field/FieldLabel вместо самодельных span, шапка блока diff дополнена заголовком «ревизия A → ревизия B» (CodeBlockTitle) слева от кнопок.	2026-09-25 22:14:02 +07:00
Denozordec	09580bbcab	feat(web): add job run timeline and code-block revision diff Раскрытие строки задачи показывает вертикальный ReUI Timeline: создана (с триггером) -> взята в работу -> результат с текстом ошибки. Diff ревизий переведён с самодельных <pre> на официальный @reui/code-block: единый блок с разметкой добавленных и удалённых строк (знаки +/- и тонировка), нумерацией, копированием и разворотом длинных списков. ResourcePage (filtered-вариант) получил поддержку expandedContent/getRowCanExpand — колонка раскрытия строится так же, как во FrameDataGrid. Точечные упрощения: прогресс BGP-сессий в мониторинге переведён на Progress из кита вместо самодельного бара; удалены @deprecated-константы ui-surface.ts, мёртвый data-grid-defaults.ts и неиспользуемый sparkline-ряд дашборда.	2026-09-25 21:46:57 +07:00
Denozordec	4d54dacd05	fix(web): localize reui grids and filters, unify ru terminology Русификация переведена на официальные i18n-слои ReUI: полный русский словарь DataGrid (lib/reui-i18n-ru.ts) подключён через data-grid-i18n во FrameDataGrid и ResourcePage — меню сортировки, «Загрузка…», «Нет данных» и пагинация больше не откатываются к английским дефолтам компонентов. Словарь фильтров дополнен ~30 недостающими ключами, каскадер в мастере проверки переведён целиком. Исправлены некорректные и разъехавшиеся лейблы: accept -> «Принять», API-триггер -> «через API», «арендатор» вместо «Тенант», «Наблюдатель» вместо «Просмотр», «Основной» вместо «Мастер (плоскость)», «AS-префиксы», «DoH-профили», колонка канбана «В очереди».	2026-09-25 21:46:24 +07:00
Denozordec	a3562cc11e	chore(web): update vendored ReUI components to latest registry Обновлены вендоренные компоненты ReUI (base-nova) до актуальных версий реестра: семейство data-grid (плюс новые data-grid-i18n и data-grid-cell-selection), filters, cascader, frame, kanban, stepper, timeline, badge, alert, icon-tile, icon-stack и новый code-block (подсветка на shiki). Shadcn-примитивы в packages/ui обновлены тем же запуском CLI. Импорты "cn" из новых файлов переведены на алиас @evobgp/ui/lib/utils, пакет cn из dependencies удалён, локальные eslint-disable в вендоренных файлах поправлены.	2026-09-25 21:45:56 +07:00
