fix: do not display the thousands separator when editing

- teach `userInputLocale` about `Locale.OmitGroupSeparator` option which
discards the said thousands separator
- some more fixes to other inputs to do the same, and align what the
validators do
- StatusAmountInput: discard illegal characters, and reuse the same
locale for the validator
- StatusAmountInputPage: make it possible to select a different locale

Fixes #14165
