Make detector use freqman (#3119 )

* make detector list a freqman file * add file loading ability, autoscan/pause, step in on pause on range, frequency value display * Update firmware/application/external/detector_rx/ui_detector_rx.hpp * Update firmware/application/external/detector_rx/ui_detector_rx.cpp * add 750 kHz step * revamp UI and add auto advance, auto scan, and only display 'RANGE SCAN...' when auto scan is on on ranges to avoid flicker of the hell. * adjust as I can the ranges as they where before * Update sdcard/FREQMAN/DETECTOR.TXT * fix instance related copilot remark
Merge updated submodule (#3116 )

+# Security Policy
+
+## Scope and Threat Model
+This repository hosts the codebase for an embedded system designed for security research. Because the system operates primarily offline, traditional network-based vulnerabilities are generally not applicable. However, we still welcome and review security reports concerning the code within this repository. 
+
+## Reporting a Vulnerability
+If you discover a vulnerability within this tool itself, please submit a report. Please be aware that the maintainers do not promise assistance with obtaining CVE IDs or managing formal security advisories.
+
+## Out of Scope
+* **Vulnerabilities found *using* this tool:** Please do not submit reports here for vulnerabilities you have discovered in other systems or targets using this tool. This channel is strictly for reporting vulnerabilities found *in* the tool itself. 
+* **Other Repositories:** For security issues concerning related tools, such as MayhemHub, please submit your reports directly to their respective repositories.
+
+## Research Attribution
+If you utilize this tool to successfully discover vulnerabilities in external systems, we would greatly appreciate it if you credit or mention our project in your published research or write-ups.
+
+## Legal and Security Disclaimer  
+For comprehensive guidelines regarding the legal and secure usage of this tool, as well as our full liability disclaimer, please refer to: [Intended-Use-and-Legality](https://github.com/portapack-mayhem/mayhem-firmware/wiki/).
