To add to what's said above: If you do manage to write there, be aware that it probably breaks FreeRTOS: we use the ccompare functionality (which depends on ccount monotonically increasing) for scheduler timing, so resetting ccount will most likely break pre-emptive scheduling.

FWIW, the V_BAT spec is missing in the current data sheet, so I think it may have been a holdover from the ESP31 days. As far as I know, 2.3V is the actual minimum, although I wouldn't be surprised if there's a 0.3V safety margin and the ESP32 will work on 2.0V in normal environmental circumstances ...
Yes. With a low _level_ interrupt, the interrupt will keep on triggering over and over again while the button is pressed, causing the CPU to execute nothing else anymore and the WDT rightfully kicking in. Neg edge probably does what you want here.

Yes, although I can imagine its location is slightly less findable. Easiest way is to disable 'Component Config -> esp32-specific -> Reserve memory for two cores'; this will also disable FreeRTOS multicore support and should keep the 2nd cpu clock gated.
