Rf improvement HEADLESS MODE (#2224)

* Fix buffers and clean up SMB/NTLM responder code

Adjust buffer sizes and validation, set TFT defaults, and refactor the SMB/NTLM responder for clarity and safety. Changes include:

- include/globals.h: increase timeStr to 16 to avoid truncation.
- src/core/settings.cpp: remove redundant >= 0 check for key delay validation.
- src/core/utils.cpp: enlarge local sprintf buffer for time formatting.
- src/modules/badusb_ble: set default TFT color to TFT_WHITE and ensure prints use a valid color.
- src/modules/wifi/responder.cpp: reorder includes, normalize whitespace/formatting, and refactor many SMB/NTLM routines (NetBIOS name encode, NTLM Type 2 builder, SMB1/SMB2 negotiate handlers, NTLM hash extraction, UI updates). The NTLM Type 2 assembly and AV pair handling were rewritten for clarity, offsets/lengths and NBSS length calculations were made explicit, and I/O (SD save, serial prints) preserved.

Overall these changes aim to prevent buffer issues, provide sane defaults for display calls, and improve maintainability and correctness of the SMB/NTLM responder logic.

* Fix

Fix compilation issue

* Add headless mode to RCSwitch_Read

Introduce a new bool headless parameter (default false) to RCSwitch_Read and propagate it to the header and implementation. When headless is true, UI operations (drawMainBorder, TFT prints, and display_info) are skipped so RF reads can be performed without touching the display. Update JS bindings to call RCSwitch_Read(..., headless=true) for headless operation when invoked from JavaScript.
