AMS Filament sync fix for locked Tool 1 & 2 (#12180)

Browse source 
Toolchanger printers with 4 tools were incorrectly treated as dual-nozzle (IDEX-style) printers in AMS Sync. So I was locked to just tool 1/2. 

Adjusted AMS Sync to use dual-nozzle logic only for true 2-nozzle setups (nozzle_nums == 2 and filament_map in {1,2}), and route 3+ tool toolchangers through the generic mapping flow so all tool IDs are handled correctly.

Tested on / with:
- Snamaker U1
- ARM macOS
