Add /drone/devices endpoint that enumerates available WiFi interfaces
(via iw/iwconfig) and RTL-SDR devices (via SDRFactory.detect_devices),
matching the pattern used by TSCM.
Sidebar WiFi interface and RTL-SDR inputs are now <select> elements
populated on init() from /drone/devices, consistent with how other
modes expose hardware selection. HackRF checkbox remains as a toggle
since it's a binary capability rather than an enumerated device list.
