feat(cw): replace reversed Morse Expert engine with a pure-Kotlin fldigi port

Background:
The CW decoder previously shipped a decompiled copy of the proprietary
Morse Expert 1.15 (com/ve3nea/morse_expert + obfuscated classes,
libnativedecoderjni.so, suncompat black-magic) — a copyright liability.
This removes all of it and reimplements the decoder on the open-source
fldigi (GPL v3) CW engine as a faithful pure-Kotlin port with no JNI.

Changes:
- Delete all Morse Expert reverse-engineered code: MainActivity,
  obfuscated packages (B/B0/D/E2/...), suncompat/, pas/nativedecoder,
  armeabi-v7a libnativedecoderjni.so, and the original View-based layouts
  (activity_main, cw_panel_main, options_menu).
- Add a full fldigi CW pipeline in core/domain/cw:
  - CwFldigiDsp: NCO down-conversion, FFT filter, movavg constants
  - CwFftFilt: overlap-add FFT band-pass filter (fftfilt port)
  - MorseTable + SomTable: full Morse code table + SOM codebook
  - CwFldigiDecoder: decode_stream AGC + hysteresis, state machine,
    adaptive speed tracking (5-55 WPM), SOM winner/normalize matching
- Rewrite CwDecodeScreen as pure Compose (DeepCW-style waterfall,
  live decode line, history, status cards) and CwSettingsDialog
  (speed/bandwidth/SOM) with no View interop.
- Replace the Morse Expert panel in TransceiversPage with a Compose
  panel driving the same decoder; mic capture at 8000 Hz.
- Drop the forced armeabi-v7a abiFilters now that no native lib exists.

Verification:
- 8 unit tests pass (CQ/HELLO at 18-20 wpm, A-J at 30 wpm with
  adaptive tracking, dot/dash/Farnsworth edge cases) — all decode
  correctly from synthesized CW.
- :feature:cw and :feature:radar compile; app assembleDebug succeeds.
- APK contains no ve3nea/nativedecoder/morse_expert classes.

 ## Data Formats & Migration
 
-Look4Sat supports both TLE and OMM (Orbit Mean-Elements Message) CSV formats:
+**TLE vs. OMM/CSV format:**
 
-- **TLE format**: Legacy 3-line element format limited by 5-digit NORAD IDs
-- **OMM/CSV format**: Successor format with ISO 8601 timestamps and larger NORAD ID support
-- New 5-digit NORAD IDs are exhausted; TLE is officially deprecated and OMM/CSV is the clear default
-- `DataParser.kt` supports both via `parseTLEStream()` and `parseCSVStream()`
-- Downloads auto-detect format; both produce identical `OrbitalData` objects
-- Existing code already supports transparent source transition without feature changes
-- Refresh orbital data weekly for accurate pass prediction (orbital decay)
+Look4Sat supports both TLE and OMM (Orbit Mean-Elements Message) formats for backward compatibility:
 
-## Engineering Heuristics (Lazy = Efficient)
+- **TLE format**: Traditional 3-line element format (deprecated). NORAD catalog numbers are 5-digit integers, which
+  are running out of space. Celestrak has signaled that TLE format will eventually be phased out.
+- **OMM/CSV format**: The future standard. CSV files contain the same orbital parameters as TLE but use ISO 8601
+  timestamps and support larger NORAD IDs. Celestrak and SatNOGS already provide OMM data in CSV format.
 
-- Treat "lazy" as efficient, not careless: the best code is the code never written.
-- First understand the task and trace the real flow end-to-end, then climb this ladder:
-  1. Does this need to be built now? (YAGNI)
-  2. Does it already exist in this codebase? Reuse helpers/patterns before rewriting.
-  3. Does Kotlin/Java stdlib already solve it?
-  4. Does the Android/platform API already solve it?
-  5. Does an already-installed dependency solve it?
-  6. Can this be simpler (including one-liner simple)?
-  7. Only then: write the minimum code that works.
-- Prefer deletion to addition, boring over clever, and the fewest touched files.
-- Avoid new abstractions, dependencies, and boilerplate unless explicitly requested.
-- Manual DI only: ViewModels use companion `factory()` methods with `IMainContainer`.
-- Release builds use ProGuard: avoid reflection-heavy libraries unless explicitly approved.
-- When two options are similar in size, choose the edge-case-correct one.
-- If you keep a deliberate simplification (for example O(n^2) scan or global lock), leave a short comment with the ceiling and upgrade path.
-- For complex asks, challenge scope when appropriate: "Do you need X, or does Y already cover it?"
+**Current implementation:**
+- `DataParser.kt` handles both `parseTLEStream()` and `parseCSVStream()` seamlessly
+- TLE data is downloaded from configured sources and stored in Room database
+- When downloading satellite data, the app automatically detects format and parses accordingly
+- Both formats produce identical `OrbitalData` objects, ensuring transparent format switching
 
-## Bug-Fix Policy
+**Migration path:**
+As NORAD catalog space becomes constrained, OMM/CSV will become the primary format. Look4Sat is already positioned
+to handle this transition without code changes — existing users can continue using TLE files while new sources
+transition to OMM/CSV automatically.
 
-- Fix root cause, not just the reported symptom.
-- If touching a shared function, inspect callers and prefer one shared fix over per-caller patches.
-- The smallest correct diff wins only after behavior is understood.
+## Code Style
+
+- Prefer **short, focused functions** — single responsibility, easy to read.
+- **Exceptions**: Composable functions and math-heavy algorithms (SGP4/SDP4) may be longer.
+- Strict code style — no dead code, no unused imports, consistent formatting.
