gui: increases default GraphRange of Network Traffic to 12 hours.

[arscynic]

1. A graph range of 12 h shows a more informative overview of the daily traffic.
2. It's annoying to increase this range after every reboot; 12 hours is right in the middle, so users who want to change it have to drag the slider less compared to the original value.

Value 6 = 30 minutes (6 * 5 m), value 144 = 12 hours (144 * 5 m).

Concept ACK

No idea what caused this error.
I edited the value in Visual Studio Code and saved it. This is the console output during the process: https://pastebin.com/FCCEHdjt. You can see I initially merged the branch to my master and pushed it, instead of pushing the branch directly—which I did afterward.

Unsure about this...

1. Running this commit, the initial displayed value is 30min, when I slider forth and back to the same position, it states 12h (bug).
2. Using a 12h window makes the graph black for a minute or so (including the grid) which is non-ideal for a user feedback (probably acceptable since not directly related to this change).

@jonasschnelli
To be a nitpicker:

1. 30 m and 12 h [in case someone tries to ctrl+f 'min']
2. ~53 seconds.

Anyway, I agree that both consequences are annoying; the former being unacceptable.

This behavior is observed on master branch too.

There doesn't seem to be agreement on doing this and the PR has been inactive for months, closing.
