- Add missing pageTitles entries so Tunnels, Files, Containers, Remote
Desktop, and Host Metrics no longer show "Glance" in the top bar
- Raise the TopBar's stacking context above the page-content section so
the user-menu dropdown no longer renders behind the hero banner
- Support editing and deleting bookmarks (not just adding), via a
shared BookmarkModal and per-row edit/delete actions in BookNest
- Standardize <select> styling globally (gold-tinted border, hover/
focus glow) instead of three inconsistent inline style definitions
- Widen cramped button padding/borders in Files and Containers
Extends the existing Engine-API-based docker integration adapter rather than
porting Termix's SSH+CLI approach, since ArchNest's docker integrations only
ever configure a baseUrl. Adds backend/src/docker/{client,exec}.ts and
backend/src/routes/docker.ts (REST + websocket exec-terminal via raw socket
hijack), and a new Containers page wired into the sidebar/router.
Verified end-to-end against a real dockerd instance and a real container in
this sandbox, which caught and fixed a genuine bug: calling /exec/{id}/resize
before starting the exec hangs the daemon indefinitely; fixed by setting the
initial size via ConsoleSize at exec-create time instead.
