Scary?: Rotors slightly contacting dust shields during hard corner (wheel bearings)

My car has stock front spindles/single piston disk brakes.

The rotors (along with the wheel bearings) were replaced ~5k miles ago when I first got my Dart back on the road. A that time, I recall looking up and following some recommendations about adjusting the tension on the wheel bearing nut but I haven't gone back to check them yet. I also remember noticing that the dust shields were a little bit bent. I did my best to tweak them back into shape but I didn't go crazy since (it seemed to me) they merely needed to clear the rotors and be left to do their job and that is how I left them- and they were just barely clearing the rotors, IIRC. I mention this because there is likely less clearance than stock...though I could measure that if it matters.

During moderately hard cornering on left hand turns, I can hear a slight "scratching" sound, seemingly coming from the front right of the car. I am 99.9% sure it is coming from the rotor making slight contact with the metal dust shields.

In all honesty, this has been going on for a long time, not getting noticeably worse or changing. Since installing more handling-related parts, I have been pushing it through corners harder and also paying more attention and suddenly, I feel like this needs to be addressed right away, preferably before a wheel departs the car mid-corner. :D

My question is this:
How much lateral movement is within spec for healthy wheel bearings?
Is it worth attempting to tighten them up a bit or would you consider this to be an immediate safety concern and replace the inner and outer bearings before driving again?
