fix: apply elevation color thresholds on radar page

LocalElevationThresholds was provided inside MainScreen, but RadarDestination
is a root-level sibling entry in NavRoot's NavDisplay, so the radar page's
top bar fell outside the CompositionLocal scope and always used the default
15/45 thresholds instead of the user-configured ones.

Hoist the CompositionLocalProvider to NavRoot so both the tab content and
the root-level RadarDestination read the user's low/high elevation
thresholds, and drop the now-redundant provider from MainScreen.

 ## Data Formats & Migration
 
-**TLE vs. OMM/CSV format:**
+Look4Sat supports both TLE and OMM (Orbit Mean-Elements Message) CSV formats:
 
-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.

-## Release Notes Must Be Bilingual (BA7OPF fork convention)
-
-Every GitHub release body carries **two sections — English first, then Chinese** (`## <tag>` each),
-listing only that release's changes, in the same order with the same claims and the same numbers.
-Both sections end with the verification line (which unit tests ran, APK signature / ABI check).
-A single-language body is a defect: fix it before the release counts as done.
-
-中文规则：每次 release 的说明必须**中英双语，先英文后中文**，两段一一对应（同一顺序、同一结论、
-同一数字，不做自由意译），只列本版改动；两段末尾都写验证情况（跑了哪些单测、签名/ABI 校验）。
-只写一种语言视为缺陷，需补齐后再算发布完成。

- *
- * Handles both layouts:
- *  - OpenSSL `-certpbe NONE`: plaintext certificate bags + a PBES2-shrouded key
- *    inside a plaintext `data` ContentInfo.
- *  - Modern TQSL: the certificate SafeContents wrapped in an `encryptedData`
- *    ContentInfo (PBES2), plus the PBES2-shrouded key in a plaintext `data`
- *    ContentInfo.

- *  - the ISS family, which SatNOGS does not list under its ARRL name "ARISS".
