feat(skd-decompile): слои 6-9 — templates (cells, merge, style, drilldown)

- Парсинг <template>/<template xsi:type=AreaTemplate>/<dcsat:TableRow>/
  <dcsat:tableCell> в rows[][].
- Распознавание содержимого ячейки: dcsat:Text → строка, dcsat:Field с
  dcscor:Parameter → "{Имя}", dcsat:Field с LocalStringType → строка/multilang,
  пустая → null.
- Merge через appearance-флаги ОбъединятьПоВертикали/ОбъединятьПоГоризонтали
  на пустых ячейках → "|"/">".
- Детект built-in стилей (header/data/subheader/total) через нормализованный
  fingerprint appearance — без сравнения per-cell ширин/высот/merge-флагов.
  При несовпадении или неоднородности — sentinel TemplateStyleMismatch.
- Извлечение widths из appearance первого row и minHeight из первой ячейки.
- Drilldown-свёртка: для cells с appearance Расшифровка=Расшифровка_X
  и template-параметром DetailsAreaTemplateParameter Расшифровка_X →
  свертываем в `{name, expression, drilldown: X}`.
- Сохранение порядка template parameters через [ordered]@{}.
- Fix namespace URI для areatemplate (`area-template` с дефисом).

Bit-perfect round-trip 55924→55924 и 28590→28590 на синтетике с header/data
стилями, merge, drilldown, шаблонными параметрами.
