Cadence gain and offset for FTMS elliptical

* Resistance must be implemented! Add support for Nordictrack GX 4.5 Pro bike

Introduces detection, initialization, and communication logic for the Nordictrack GX 4.5 Pro bike model. Updates settings, device handling, and UI to allow selection and configuration of this new bike type.

* Update proformbike.cpp

* Update proformbike.cpp

* Fix resistance write logic in innerWriteResistance

Moved the return statement to ensure true is returned after setting resistance, regardless of whether the requested resistance matches the current value. This clarifies the function's behavior and ensures correct signaling after resistance changes.

* Increment allSettingsCount from 855 to 856

* Update proformbike.cpp

* Update proformbike.cpp

* Update proformbike.cpp

* Add handling for additional ProForm bike models

* Fix indentation and remove unnecessary break statement

 4. Update `qdomyos-zwift.pri` with new source files
 5. Add tests in `tst/Devices/` following existing patterns
 
+### Adding Device Detection to bluetooth.cpp
+
+**CRITICAL: Always verify device pattern conflicts before adding to bluetooth.cpp**
+
+When adding a new device pattern to `src/devices/bluetooth.cpp`, you **MUST** follow these verification steps:
+
+1. **Search for Similar Patterns**: Use grep/search to find all existing device patterns that might conflict
+   - Search for device name prefixes (e.g., if adding "KS-NG-", search for all "KS-" patterns)
+   - Check patterns in all device type cases (bikes, treadmills, ellipticals, rowers, etc.)
+
+2. **Analyze Pattern Specificity**: Understand the pattern hierarchy
+   - More specific patterns should be checked BEFORE less specific ones
+   - Example: "KS-NGCH-" is more specific than "KS-NG-"
+   - The order matters: devices are matched by the FIRST matching pattern in the if-else chain
+
+3. **Check Case Order**: Verify the order of device type cases in bluetooth.cpp
+   - Earlier cases take precedence over later cases
+   - Ensure more specific patterns in earlier cases won't prevent your pattern from matching
+   - Ensure your pattern won't incorrectly match devices intended for other cases
+
+4. **Document Conflicts**: When conflicts exist, verify they are intentional
+   - More specific patterns earlier in the chain should catch specific devices
+   - Your pattern should only catch devices not matched by more specific patterns
+   - Example: "KS-NGCH-X21C" (kingsmithR2Treadmill) should match before "KS-NG-" (horizontreadmill)
+
+5. **Test Pattern Matching**: Consider these scenarios
+   - Will your pattern match the intended device? (e.g., "KS-NG-X218")
+   - Will it incorrectly match other devices? (e.g., "KS-NGCH-X21C")
+   - Are there existing patterns that would match your device first?
+
+**Example Verification Process:**
+
+```bash
+# Search for similar patterns
+grep -n "KS-" src/devices/bluetooth.cpp
+
+# Review each match for conflicts
+# - kingsmithR2Treadmill has "KS-NGCH-X21C" (line 1323)
+# - horizontreadmill has "KS-MC" (line 1562)
+# - Adding "KS-NG-" to horizontreadmill is safe because:
+#   1. "KS-NGCH-" patterns are more specific
+#   2. kingsmithR2Treadmill case comes first (line 1312 vs 1560)
+#   3. "KS-NG-X218" won't match "KS-NGCH-" patterns
+```
+
+**Common Pitfalls:**
+- Adding a pattern without checking existing patterns
+- Not considering pattern order in the if-else chain
+- Adding overly broad patterns that match unintended devices
+- Not testing with actual device names
+

+## Updating Version Numbers
+
+When releasing a new version of QDomyos-Zwift, you must update the version number in **3 files**:
+
+### 1. Android Manifest
+**File**: `src/android/AndroidManifest.xml`
+
+Update both `versionName` and `versionCode`:
+```xml
+<manifest ... android:versionName="X.XX.XX" android:versionCode="XXXX" ...>
+```
+
+- `versionName`: The human-readable version (e.g., "2.20.26")
+- `versionCode`: Integer build number that must be incremented (e.g., 1274)
+
+### 2. Main QML File
+**File**: `src/main.qml`
+
+Update the version text displayed in the UI (around line 938):
+```qml
+ItemDelegate {
+    text: "version X.XX.XX"
+    width: parent.width
+}
+```
+
+### 3. Qt Project Include File
+**File**: `src/qdomyos-zwift.pri`
+
+Update the VERSION variable (around line 1011):
+```pri
+VERSION = X.XX.XX
+```
+
+### Version Numbering Convention
+
+- **Major.Minor.Patch** format (e.g., 2.20.26)
+- **Build number** must always increment, never reuse
+- Update all 3 files together to keep versions synchronized
+
+### iOS Version (Optional)
+
+iOS version is managed through Xcode project variables:
+- `MARKETING_VERSION` in project.pbxproj (corresponds to versionName)
+- `CURRENT_PROJECT_VERSION` in project.pbxproj (corresponds to versionCode)
+
+These are typically updated via Xcode IDE rather than manually editing files.
+
 ## Additional Memories
 
 - When adding a new setting in QML (setting-tiles.qml), you must:
-  * Add the property at the END of the properties list  
+  * Add the property at the END of the properties list
