feat(skd-decompile): расширенные role (object form) + silent-drop visibility

- Get-RoleInfo (вместо Get-RoleTokens): любой dcscom:KEY=true → @KEY;
  accountTypeExpression/balanceGroup → extras → object form role
  (compile уже поддерживает object form через {key: true})
- Build-Field: object form role при наличии extras
- Silent-drop → warnings (без ломания round-trip):
  * Check-InputParameters — ChoiceParameters/ChoiceParameterLinks (non-empty)
  * orderExpression на field
  * scope в conditionalAppearance item

На сэмпле 30 ERP-отчётов: 754 → 147 sentinel'ов (-80%), 8/30 clean.
