… crashing Formly number parser
@ngx-formly/core's json-schema integer/number parser reads
document.querySelector('#'+field.id).validity.badInput, assuming the id is on the
native <input>. ng-zorro's nz-input-number puts the id on its host element, which has
no .validity, so the parser throws 'Cannot read properties of undefined (reading
badInput)' whenever the parsed value is null (an intermediate state while typing).
Typed edits then never commit and the field is stuck (only the +/- steppers work).
Replace the numeric fields' parser in jsonSchemaMapIntercept with a null-safe parser
that does no DOM access.

What changes were proposed in this PR?
Fixes typed edits being ignored on integer/number operator property fields (reproduced
on the Limit operator): the field gets stuck and only the +/- steppers work.
Root cause:
@ngx-formly/core's json-schema integer/number parser readsdocument.querySelector('#' + field.id).validity.badInput, assuming the id is on thenative
<input>. ng-zorro'snz-input-numberputs the id on its host element (whichhas no
.validity), so the parser throwsCannot read properties of undefined (reading 'badInput')whenever the parsed value is null (an intermediate state whiletyping). The typed value then never commits.
This replaces that parser, for numeric fields only, with a null-safe parser that does
no DOM access (
applySafeNumericParserinjsonSchemaMapIntercept). The stepper pathwas unaffected and keeps working.

How was this PR tested?
parseNumericInput(numeric/decimal/negative/whitespace/empty/non-numeric/DOM-safety) and
applySafeNumericParser(replaces the crash-prone parser,null-safe on the clear-field case, leaves non-numeric fields untouched) — 12 tests.
OperatorPropertyEditFrameComponentspec still passes.and the console
badInputTypeError is gone.Was this PR authored or co-authored using generative AI tooling?
