What is on the other side of the board?
There is a fuse warning - where is the fuse?

The terms heat and moto next to your connections and the
big traces imply a lot of current

i think the star pattern is for high current and it is special to this design
standard through hole pads are rectangular or round or oval

Much of what you see in PCB layouts comes from personal styles, but in this particular case if there was any science behind perhaps the designer believed that by adding vias around the PAD that undergoes mechanical stress on the connector at the opposite side, it could somehow 'sew' the copper sheet more strongly on the board's surface.

Faston terminals, as supposed; this type of connection should not be used in phenolite boards because after a certain amount of handling break the weld. and detach the copper track right below.

It isn't a pad, its solder resist mask. It would normally be included in the footprint of the blade connector but it should be easy enough to create if you need it for something else. It does increase the current capacity but it is mostly to add rigidity to the terminal which obviously will need some pressure to connect or disconnect a cable to.
