Add power limits and model detection for ASUS TUF Gaming A14 FA401EA (AI MAX 392) (#5027)

- Add IsFA401EA() helper to AppConfig for consistent model detection style
- Set MaxTotal and MaxCPU to 115W for FA401EA (AMD AI MAX 392)
- Change MaxCPU from const to static to allow runtime override
- Register FA401EA in IsAMDiGPU() and NoGpu() (iGPU-only, no discrete GPU)
