Modifications to kamp/Start_Print.cfg to address mesh and bed temperature issues

[smartc]

Thermal Stability: Added BED_TEMP={bed_temp} to the CX_NOZZLE_CLEAR call to prevent the bed from reverting to default temperatures during the cleaning cycle.

Heat Soak Dwell: Added a conditional 2-minute soak (G4 P120000) for bed temperatures ≥75°C to allow for thermal expansion before homing/probing.

Logic Optimization: Reordered the sequence to ensure the nozzle is cleared, Z is re-homed (ACCURATE_G28) and bed leveling occurs after the bed has reached target temperature and stabilized.

Debug Logging: Added RESPOND messages to the console to provide better visibility into the macro's progress and the "prepare" logic path.

I was experiencing issues with poor ASA first layer quality. Traced it back to an issue with my bed warping significantly between the default 50C temperature (good for PLA and ok for PETG) and the 100C I was using for ASA. Re-sequenced a few things in the start macro to address this.

Likely better ways it could be optimized, but this is working for me - finally getting reliable prints with ASA. Wanted to ensure others with this issue are able to benefit as well.
