merge: upstream rt-bishop main (18 commits) with conflict resolution

Merges rt-bishop/Look4Sat main (a42a5f1f, 18 commits: AMSAT status page,
customizable data sources, Doppler calculator, radar compass offset, per-sat
offset memory, localized date formats) into the fork's 30-commit audit
baseline.

Conflict resolution policy (user-directed):
- AMSAT feature (AmSatRepository, SatStatusScreen/ViewModel, SatStatus model):
  upstream version, which the user judged better built. MainScreen routes
  Screen.AmSat through SatStatusDestination().
- Localization: our values-zh/values-tr restored (upstream's merge dropped the
  fork-only strings); new upstream strings (sat_group counts, compass offset,
  frequency offset help) added in EN + ZH.
- fork-only features kept (CW decoder, Mutual/Roaming, WaveLog, APRS, Log tab,
  custom TLE/transceiver source switches): ours.
- Both sides' additions merged where independent: radar compass offset fields
  (Settings/SettingsRepo/RadarState), calculatorOffsetKHz action, wider linear
  transponder detection, deduplicateTransponders + its tests, sunrise/sunset
  tests merged with the moon hour-angle test.
- Sources kept as the fork's map structure (DatabaseRepo depends on it);
  satelliteModes list re-added for SelectionRepo. getSatelliteTypesIds /
  setSatelliteTypeIds re-added to ISettingsRepo+SettingsRepo; SharedDialog
  re-added to Components; providePairedBluetoothDevices added to
  IMainContainer/MainContainer.
- Icons renamed upstream (ic_satellites->ic_sputnik, ic_radar->ic_satellite)
  applied to Navigation/MutualScreen.

Build verified: all modules compileReleaseKotlin + unit tests
(core:domain, core:data, feature:map, feature:roaming) green.

 ## Data Formats & Migration

-Look4Sat supports both TLE and OMM (Orbit Mean-Elements Message) formats for backward compatibility:
+- **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)
 
-- **TLE format**: Traditional 3-line element format (deprecated). NORAD catalog numbers are 5-digit integers, which
+## Engineering Heuristics (Lazy = Efficient)
-  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.
 
-**Current implementation:**
+- Treat "lazy" as efficient, not careless: the best code is the code never written.
-- `DataParser.kt` handles both `parseTLEStream()` and `parseCSVStream()` seamlessly
+- First understand the task and trace the real flow end-to-end, then climb this ladder:
-- TLE data is downloaded from configured sources and stored in Room database
+  1. Does this need to be built now? (YAGNI)
-- When downloading satellite data, the app automatically detects format and parses accordingly
+  2. Does it already exist in this codebase? Reuse helpers/patterns before rewriting.
-- Both formats produce identical `OrbitalData` objects, ensuring transparent format switching
+  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?"
 
-**Migration path:**
+## Bug-Fix Policy
-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.
 
-## Code Style
+- Fix root cause, not just the reported symptom.
-
+- If touching a shared function, inspect callers and prefer one shared fix over per-caller patches.
-- Prefer **short, focused functions** — single responsibility, easy to read.
+- The smallest correct diff wins only after behavior is understood.
-- **Exceptions**: Composable functions and math-heavy algorithms (SGP4/SDP4) may be longer.
-- Strict code style — no dead code, no unused imports, consistent formatting.
