[FEAT] Database last update

[StephanCassel]

Hi, Excellent 👍 software. Used it for many years. I am using Syncthing software between mobile and all home computers. Keepass is synced every time I add or change any items in the KP database independently where it changed. Works like a charm.

It would be smashing if Keepass shows the last edit database date on the front/login. Then it would be easier to determine if sync has been successful.

Thanks in advanced
