Theseus 0.3.65: Updates panel can't silently fatal into "Loading…" any more

Settings › General › Updates used to stay on "Loading…" forever if anything
earlier in the shared C.get().then((s)=>…) init threw, or if the version IPC
rejected — the .catch(()=>{}) on the version fetch swallowed it. Users then
had no in-app way to run "Check for updates", because the button sits in the
same panel.

Panel init now wraps in its own try, surfaces the actual error on the status
line (missing IPC / fetch rejection / init failure), and keeps the Check for
Updates button functional even when the earlier version read fails. Toolbar
chip is unaffected either way — the auto-updater runs independently.
