TableNG: Text wrap enhancements (#102954)

* feat: text wrap table g12 * chore: remove stale comment * tests: skipping - can't figure out how to test right now * move text wrap stuff to table new * chore: make table stuff untouched. only in table new * wrap text stuff only in table-new * unbreak RT wrapping * skip tests for now * cleanup * fix bad merge * revert some stuffs * maybe * tweaks * uwrap 0.1.1 * fix: cell width fixes for overrides * chore: fix column width * fix: update hover logic * fix: utils.test.ts * chore: mock uWrap and remove tests for now * chore: adjust width * chore: clean * chore: width passed to uwrap account for border * chore: width changes * adjust * no descr --------- Co-authored-by: Leon Sorokin <leeoniya@gmail.com>
