feat: auto cue re-numbering (#2016)

* feat: update auto cue numbering * feat: renumber from ui * refactor: patchEntries is not used * chore: format * fix: correct cue at top of group * fix: handle precision * refactor dialog * bump limit for performance time test * extract type * add class name to lable * fix rebase * refator: extract renumering logic * chore: comments for getIntegerAndFraction function * chore: add the for renumber mutation * fix: fraction match precision * refactor: small cleanup * refactor: use more narrow validator --------- Co-authored-by: alex-Arc <omnivox@LAPTOP-RC5SNBVV.localdomain>
