the Wheels are not centered in the frame or fork correctly.
the slight misalignment of the pads (front to rear) you see is not an issue on the rear brake, but is an issue on that front brake/fork.
check to verify one of the pads is not upside down... and yes, brake caliper arms do get bent sometimes... the alignment of the vertical pad adjust slots can be eyeballed to find a bent arm... wheel out, possibly remove the pads, and compare the slots.
Front calipers are the most susceptible to getting bent... from impacts or storage mistakes.
the wheels not being centered is an issue to be concerned about.
did you install the front wheel with the bike upright? if so, the axle is not fully seated in the dropouts.
the rear wheel is only slightly out of align... a slightly smaller axle diameter can cause that much of a misalignment, or an incorrectly centered hub/rim, or poorly done "truing" job can do that.
