There's nothing to limit the current when capacitors fail, so that failure

X rated capacitors use fusible coatings, so a short causes a burn out
of the conductor around the short. The overall capacitance is not
noticeably affectde, IOW its self healing.
I doubt that. The diodes will probably open, and I used really skinny wire.
Very fine wire sounds like effective fusing to me.
You only need 20mA of AC current to cause ventricular fibrillation.
If the capacitor fails, someone could get killed touching whatever
your circuit connects to.
