We know they have not disabled Bluetooth in bookworm.And have they disabled Bluetooth in config.txt?
The real problem is not that omission, but all the extra™. Just raspi-config should be enough to enable a basic UART. Then there are a few model-specific quirks and options, which are clearly documented. https://www.raspberrypi.com/documentati ... gure-uarts
dtoverlay=uart0,param=val is intended for pin mapping on Compute Modules. It does not make much sense on retail Pies, because the second bank of GPIOs is not available. With no params at all, dtoverlay=uart0 appears to mean that you want UART0 on GPIO14/15, regardless of whether the rest of your configuration enables a Linux driver for it!
Furthermore, OP has installed WiringPi and used its gpio utility in rc.local to force GPIO14/15 to ALT0. Again that is worse than useless. It should never be necessary, but it may route signals to a different UART than the one you have a driver for. "No traffic" is exactly the likely result.
Generally, "performing the same steps" only works if there is a coherent reason that the steps were correct.
