Bump handsontable and @handsontable/angular-wrapper 17.1 -> 18.0 and
adapt to its stricter TypeScript-core types: moved handsontable/common
and deep walkontable imports to their new public export paths, added
explicit generics/casts where getData()/getCellMeta()/getSelected() are
now typed unknown/nullable instead of the loose v17 shapes, and updated
the AutocompleteEditor override to the new open() signature.
Also allowlists @handsontable/angular-wrapper@18.0.0 and
handsontable@18.0.0 in licenseChecker.js — both versions report the
same non-SPDX "SEE LICENSE IN LICENSE.txt" field that license-checker
mis-resolves as a disallowed custom license, same as prior versions.
