Browse source 
* [FL-2431] SubGhz: fix Restart with an error (HardFault), while maintaining the RAW signal.
* Stream: fix adding maximum string length to arguments
* [FL-2419] SubGhz: fix flipper hang/Fatal Error when running edited Sub-GHz file.
* SubGhz: remove replace strcpy with strncpy, smaller text buffer and canary
* SubGhz: log key loading before load happen, rollback only rx message handling
