Subject: [PATCH] Phase 5 (D4 fix): daemon shares GUI config dir (EWSDR app
 name)

GetAppConfigDir derives the dir from ApplicationName, which defaulted to the
binary name 'ewsdrd' -> a separate empty ~/.config/ewsdrd/. With no per-device
settings the daemon never configured WDSP's FFT/spectrum/waterfall display (web
showed a white waterfall and no spectrum), never resolved a saved board type
(Board=0), and -- critically -- found no FFTW wisdom, so WDSP recomputed it from
scratch on Open (~48s vs <1s in the GUI). Set OnGetApplicationName := 'EWSDR'
(matching the GUI's Application.Title) before constructing the controller, so the
daemon reads the same ~/.config/EWSDR/ (settings, saved devices, wdspWisdom00).
