fix(skd-validate): eliminate false positives on real ERP/БП reports

Calibrated against 1106 vendor reports (ERP 8.3.24 + БП 8.3.27).
Three categories of false positive removed:

- CalculatedField with empty <expression/> demoted error→warning.
  Three legitimate vendor patterns surfaced:
    * sibling totalField with same dataPath provides the formula
      (used in cancellation-rate and share-percentage reports)
    * groupTemplate references the field as group name
    * field exists only as a declarative anchor for settingsVariants
  Warning preserved so genuinely-missing formulas still surface.

- Duplicate template name demoted error→warning. Vendor configs ship
  reports (БазаНормируемыхРасходов/Выручка) with three <template> blocks
  named Макет1 — the platform identifies templates by position, not by
  <name>. Warning still flags the collision without failing validation.

- comparisonType whitelist extended with NotInHierarchy and
  NotInListByHierarchy. Existing list was missing the negated
  hierarchy operators used in 20 of the 1106 reports.

Result: 0 false positives across the corpus, all genuine errors still
caught (verified separately against intentionally-broken fixtures).
