fix: trigger onChange when manually clearing input via select all + delete

alii13 · alii13 · commit d5bba8db35f2 · 2025-10-27T16:00:56.000+05:30
When users manually select all text (Ctrl+A) and press Delete/Backspace,
the onChange callback is now properly triggered with null, matching the
behavior of the clear button.

Previously, the input would reset to the previous value on blur without
triggering onChange, which was inconsistent and prevented users from
clearing dates via keyboard.

Changes:
- Modified useInputProps to detect empty input and trigger onChange(null)
- Added handlers in Input component for both formatted and non-formatted inputs
- Updated SingleSelector to properly handle null values by calling onClear
- Added comprehensive test coverage with 11 new tests

Fixes: #52473 (ant-design/ant-design)

All existing tests pass (453 tests), ensuring backward compatibility.
