ci: path filters + buildkit cache для ускорения сборки

Цель: типичный push должен катиться за 30-60 сек вместо 3-5 мин.

docker.yml — две оптимизации:
1. Job changes детектит что изменилось (api/web) через `git diff
   HEAD~1 HEAD`. Образ пересобирается только если затронуты его
   директории; `paths-ignore` отсекает docs/*.md/.github/**.
2. Сборка через `docker buildx build` с registry-cache:
   --cache-from / --cache-to type=registry,ref=...:buildcache,mode=max.
   Локальный 127.0.0.1:5001 уже разрешает DELETE, так что mutable
   buildcache работает. dotnet restore / pnpm install теперь почти
   мгновенные при отсутствии изменений в *.csproj / pnpm-lock.yaml.
3. deploy-stage запускается только если api или web реально
   пересобирался; для пропущенного образа в .env пишется :latest,
   compose pull тянет последний успешный slim. Telegram-сообщение
   указывает что именно деплоилось ([api web] / [web] / только compose).

ci.yml — actions/cache для NuGet (~/.nuget/packages по hash *.csproj)
и pnpm store (по hash pnpm-lock.yaml). paths-ignore такое же.

POS-job (windows-latest) не трогаем — он и так fires только на
тег v* / workflow_dispatch.
