fix(cw): repair FFT pipeline (NaN twiddle table + dead cond_22 path)

The waterfall showed mirrored/upside-down garbage because the FFT
never produced a valid spectrum:
1. g3.c.f() (high-precision sin) had its quadrant-0 case mangled by
   jadx into a nested-if that returned NaN for small angles - the
   twiddle factor table ended up with 329/1024 NaN entries.
   Restored the smali switch: case0->g(), case1->c(), case2->-g(),
   case3->-c().
2. i3.d.k() routed the runtime FFT (a5==0, single-thread path) into
   the else of if(a5!=1) instead of if(a5!=0), so the FFT never ran
   and the output stayed in the time domain (peak at bin 357 for a
   669Hz tone instead of bin 86).

Verified with a JVM harness (static-block tables + pure-tone inputs):
200Hz->bin26, 400Hz->bin51, 669Hz->bin86, 1000Hz->bin128, all exact.
Twiddle table NaN count: 329 -> 0.

feat(cw): port Morse Expert 1.15 CW decoder engine (feature:cw compiles)

Full port of the CW/Morse decoder from Morse Expert 1.15
(com.ve3nea.morse_expert), preserving obfuscated class names and logic.
Ads (gms.ads), billing (BillingClient), and library code were removed per
user; SettingsActivity deferred to Compose integration.

Ported modules:
- pas.*: decoder engine interface + JNI (libnativedecoderjni.so, armeabi-v7a)
- k3.*: FFT library (pseudo-enum q rewritten from smali; sun.misc stubs
  for Unsafe/Cleaner since Android lacks them; FFT path uses float[] branch)
- i3.*, g3.*, j3.*, s.*, d1.AbstractC1518b: DSP/sin-cos tables (long[] tables
  f/f11589g restored from smali)
- H2.a/b: audio capture + decode control core (jadx catch-block illusions
  cleaned per smali; recording try/catch restored around write block)
- J2.a/b: waterfall OpenGL renderer + palette (r10 = anchor color per smali)
- E2.g: waterfall touch frequency picker (height = ScaleView per smali)
- B0.b/B.RunnableC0001b: status-bar + decoded-text UI runnables (real
  constructors recovered from smali)
- MainActivity → controller class (Activity injected; immersive status bar
  inlined); C1646n trimmed to view holder; D.n keeps waterfall texture case
- F2.a: text selection menu (Save/Share)

Verified: :feature:cw:compileDebugJavaWithJavac BUILD SUCCESSFUL.
