On macOS Cocoa, TBitmap.pf32bit stores pixels in ARGB order
(byte0=A, byte1=R, byte2=G, byte3=B) rather than BGRA used on
Linux/Windows. All raw ScanLine pixel blending and channel mapping
is now guarded with { DARWIN} to use the correct offsets.
Also fix PortAudio library discovery on macOS: probe .dylib names
(including Homebrew paths) before falling through to .so/.dll.
AGC button in DSP row shows current mode (FAST/MED/SLOW/LONG/OFF).
Click toggles a picker row below; selecting a mode closes it, fires
OnAGCChange, and syncs MainForm BtnAGCMode buttons and DSP engine.
Overlay height expands 136→159 px while picker is open.

Third button row mirrors MainForm NR (cycle 0-4), NB (cycle 0-2),
SNB and ANF toggles. OnDSPChange event syncs state back to MainForm
buttons and DSP engine. Overlay height tightened to match top/bottom
padding.
