fix(files_sharing): Improve expiration date input change handling

If the time picker component is emitting a Date object already, then there is redundant call of `new Date(new Date())` and

therefore introduces subtle bugs, for example on chrome users could not  enter expiration date with keyboard.

- Use @update:model-value instead of @change/@input for more reliable date updates

- Ensure null and invalid dates are handled correctly in onExpirationChange

- Validate date input before updating defaultExpirationDateEnabled

Resolves : #51875
