AI summary

FW Lite Web logged TroubleshootingService method GetSettingsFile failed on every load (and, since #2765, sent a matching Mixpanel error event). The Troubleshoot dialog fetched the settings file unconditionally, but web doesn't expose GetSettingsFile.

• Add ITroubleshootingService.GetCanManageSettingsFile(), following the GetCanShare() pattern: MAUI returns true, web returns false.
• GetVerboseLogging() now returns bool instead of overloading null to mean "no settings file". On web it is no longer [JSInvokable] and throws NotSupportedException, like the other settings methods.
• TroubleshootDialog.svelte loads verbose logging and the settings file, and shows both controls, only when the host can manage the settings file. MAUI behaviour is unchanged.
• Regenerated TS types.

Test plan

• MauiTroubleshootingServiceTests pass (net10.0)
• task verify in frontend/viewer
• FW Lite Web: open home page and Troubleshoot dialog, no GetSettingsFile error in the console
• FW Lite (MAUI): Troubleshoot dialog still shows the verbose logging switch and the settings file editor

Walkthrough

The troubleshooting service contract adds a settings-file capability method and changes GetVerboseLogging() to return a non-nullable boolean. The MAUI implementation reports settings-file support, while the web implementation reports no support and throws when verbose logging is requested. The troubleshooting dialog uses the capability result to gate settings-file access and controls.

If the capability query fails, the settings controls disappear without an error message. The change is otherwise mergeable with awareness of this bounded issue.

Web says, “Not this while.”

- Line 41: Update the TroubleshootDialog flow around canManageSettingsFile so
errors captured when getCanManageSettingsFile() rejects are forwarded to the
global error handler; preserve the existing capability-query behavior otherwise.
