The standout thing to me is that you've no communication with any door module:
Address 42: Door Elect, Driver
Cannot be reached
Address 52: Door Elect, Pass.
Cannot be reached
Address 62: Door, Rear Left
Cannot be reached
Address 72: Door, Rear Right
Cannot be reached
It's somewhat unusual to lose all four so I'd be checking for common points of failure, ie power or CAN-bus.
I haven't got a wiring diagram for a Superb but I'd replace the fuse and check the fusebox contacts are in good condition, it's probably called the 'central locking control module' and at least on a MK2 Octavia, it's fuse 12 (10A) in the dashboard end fuse panel. It's probably the same for a Superb but check
If that makes no change, check the door modules are getting power on pins T20d/12 and T20e/12. There are separate fuses which feed the electric windows but I don't think they are needed for the modules to communicate. Pretty sure the rear modules aren't 'proper' modules so I'd be concentrating on the front modules for now.
Once you've verified the modules have power (and ground), I'd then suspect either broken or shorted CAN-bus wires. They'll be harder to track down but the door gaiters are an obvious starting point. If there's nothing obvious, you should do a proper test of the wiring between the CAN gateway and the door modules.
TBH, given there are no obvious faults in the CAN gateway about CAN-bus issues/shorts/1-wire mode etc, it feels like power is a more obvious fit.
As for the other faults:
- Address 05 and 09 are almost certainly a side-effect of the missing door modules
- Address 08 are unlikely the cause or will help diagnose this, could be a side-effect
- Address 19 is expected (radio/nav removed, door modules are sad)
- Address 2E is expected as the radio/nav is removed
- Address 47, check the tweeter and wiring to front right door
- Address 6D no idea, could be a side-effect
- Address 77 is also due to the radio/nav replacement
