[WIP] **_{_{}} Legacy UI not started after webview failure in reconnect path**

[Copilot]

Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.

Original issue description:

Legacy UI not started after webview failure in reconnect path

When the app starts in fallback mode and later _open_webview_after_fallback() schedules a webview launch, run() exits the Tk loop, sets pending_webview and calls start_webview_runtime() (lines 882‑884). If webview.start() raises an exception, the new code builds the legacy interface and sets force_legacy_ui inside start_webview_runtime() (lines 892‑914) but then returns False. Because run() does not re‑enter self.root.mainloop() after this call, the newly created Tk window never runs and the process simply terminates. Users who lose the webview during the reconnect flow will be left without any UI. Consider re‑starting the Tk main loop (or looping) when start_webview_runtime() fails so that the legacy UI actually appears.

Useful? React with 👍 / 👎.
