Calendar: 12h time picker changes from 12 am to 12 pm automatically

[dmhendricks]

Describe the bug

If the 12-hour time picker contains a time between midnight and 1am, it will automatically switch to pm if a new date is selected. Previously mentioned in #4449.

This has caused a number of scheduling incidents with users when they pull up a document, change the date, and don't notice that the am subtly and automatically changes to pm.

Steps to reproduce the behavior

You can reproduce it on the current v3.46.0 documentation page demo:

1. Go here: https://primevue.org/calendar/
2. Select a date and time. Make the time 12:xx AM. Example:

3. Click off of field to remove focus (you can click anywhere else on the page)
4. Click on the field again and select any date (don't touch the time, just change the date). When you do that, the "am" will automatically change to "pm" even though the time wasn't changed/touched:

Expected behavior

If you click the field to change the date, the time that was previously selected should be preserved rather than automatically switching from am to pm.
