fix(companion): app webview content clears the status bar; HTTPS toggle on add/edit — 0.5.21

- In-app browser pages (node apps) now start below the status bar again:
  the WebView stays edge-to-edge (page colour fills the bar) and a
  body{padding-top:<statusbar>} injection pushes content down — the
  pre-edge-to-edge look without the black bar.
- Add/Edit server in the menu now has a Use HTTPS toggle (was scheme-locked;
  edit preserved the old scheme, add forced http).
