feat(ui): add Classic, Smart, and Compact desktop navigation styles (#1642)

* feat(ui): add Classic, Smart, and Compact desktop navigation styles

Introduce a shared app-nav registry and reachable model so TopBar, the
command palette, and mobile menus share one destination source. Smart bar
is the default; Appearance gains a Navigation subsection with quick links.

* fix(e2e): stop clearing top-nav prefs on every reload

The desktop-navigation suite used addInitScript to wipe mode storage,
which re-ran on reload and undid the classic/compact values under test.

* fix(ui): harden nav PR docs and Compact quick-link coverage

Drop the partial docs-refresh import that left missing image assets and a stale Display screenshot, keep navigation-scoped operator docs against main, and add an E2E path that proves Compact quick-link add, persist, and render after reload.

* fix(ui): polish Compact quick links and menu mastheads

Align Smart/Compact menus with Theme chrome, keep pin labels always visible, and drive add capacity from persisted pins (max five) with a trailing + picker and per-pin remove.

* test(e2e): exact-match Compact Networking pin locator

Avoid Playwright strict-mode clash with Actions for Networking.

* fix(ui): simplify Compact quick link removal and fix + button trailing

Remove the (...) dropdown per quick link in Compact mode. Right-click
context menu remains as the sole on-bar removal affordance. Fix the +
add-button to trail quick links rather than pinning to the far right
by removing flex-1 from the quick-link rail.

+The top navigation starts with **Home**, **Resources**, **Networking**, **Security**, and **App Store**. **Fleet** appears when your role can read nodes. Additional operator views (**Logs**, **Update**, **Schedules**, and **Audit**) appear based on your role and license tier. **Console** is a limited-availability operator surface documented on its own page when enabled on an instance. Fleet-wide views describe the control instance, so they are hidden while a remote node is active. Choose Classic, Smart, or Compact desktop navigation under **Settings → Appearance → Navigation**; phone navigation stays on its own layout.

 The left sidebar is the stack workspace. Below the Sencho brand, it starts with the node switcher, then **Create Stack**, a bulk-mode toggle, and **Scan stacks folder** for re-indexing compose projects added outside Sencho. Use **Search stacks...** with the **All**, **Up**, **Down**, and **Updates** chips to narrow the list. On a fresh install with an empty stack list, Sencho scans your mounted compose directory automatically and shows what it found, including compose files that still need to be adopted into their own subfolder.
