Add serial console support, remove wrong debug UART patch
Enable GPIO UART0 on Pi5/CM5 via dtoverlay=uart0-pi5 in
configTxtAppend. Remove the old 0002 patch that targeted the
debug UART (ttyAMA10) — Compute Blade uses GPIO 14/15 (ttyAMA0).
Renumber overlay patches (old 0003 becomes 0002).

Update README with tested serial console docs: wiring diagram,
even parity config, 3.3V requirement, and read-only limitation.
