Just modifying some margins, to provide more space. To make it work better, especially in portrait.

I was testing the changes on Nemo-mobile-wayland, on N950. It was frustrating when zypper-update just erased all my efforts. So I am putting them there, in hopes that they will be included in next update.
Yes, having seconds inside time may seem petty. Especially inside alarm time. But a user has right to see seconds on the clock. Especially since you already update the time every second.
