Port the ScadaLink CentralUI sidebar pattern into the OtOpcUa AdminUI:
- Drop the top app-bar. Brand moves into the side rail's header — same
visual rhythm as ScadaLink's NavMenu.
- New NavSection.razor: collapsible eyebrow toggle (rail-eyebrow-toggle CSS)
with a chevron + label. Mirrors ScadaLink/Components/Layout/NavSection.
- New NavSidebar.razor: interactive island carrying the three section
groups (Navigation / Scripting / Live) + session block. Marked
@rendermode InteractiveServer; MainLayout itself stays static-rendered
because layouts can't take a RenderFragment Body across an interactive
boundary.
- New wwwroot/js/nav-state.js: window.navState.get/.set persists the
expanded-section list to the otopcua_nav cookie (one-year lifetime,
SameSite=Lax). Same shape as ScadaLink's scadabridge_nav.
- New LoginLayout.razor + @layout LoginLayout on Login.razor: the login
page now renders without the side rail — clean centred card.
- MainLayout.razor: slimmed down to the d-flex shell + hamburger toggle +
<NavSidebar/> + @Body.
- Login.razor: also drops the trailing "LDAP bind against the configured
directory..." footer that the user asked to remove.
- site.css: adds .side-rail .brand styles (mirrored from ScadaLink) and
the .rail-eyebrow-toggle / .rail-eyebrow-chevron / .rail-section-body
styles for the new collapsible UI.
Auto-expand on page load: NavSidebar seeds the expanded set from the
current URL's first path segment (in OnInitialized so it works even on
the very first server render) and from the cookie (in OnAfterRenderAsync
once JS interop is available). LocationChanged hooks keep the expanded
state in sync as the user navigates between sections.
Implements Phase A of the F15 rebuild plan: minimum-viable Admin surface
with a working sign-in path and a fleet-state landing page. Decisions Q1–Q5
of docs/v2/AdminUI-rebuild-plan.md were taken as recommended.
- App.razor (moved into AdminUI library from the Host stub; vendored
Bootstrap from RCL wwwroot — no public CDN, air-gap safe)
- Routes.razor (AuthorizeRouteView enforces page-level [Authorize])
- RedirectToLogin.razor (preserves returnUrl through the auth hop)
- Login.razor (static SSR, posts to /auth/login; Q5 wording about
generic-vs-specific LDAP errors)
- Account.razor (identity + fleet roles + raw LDAP groups; Q4 — no
per-cluster grants; fleet-wide LDAP-group → role mapping only)
- Fleet.razor (per-node deployment status: reads NodeDeploymentState
+ unions with IClusterRoleInfo.MembersWithRole("driver") so freshly-
joined nodes appear as "waiting"; 10s auto-refresh)
- Hosts.razor (Akka cluster topology: members, status, roles, role-
leader; 5s auto-refresh)
Host's stub App.razor deleted; Program.cs now points at
AdminUI.Components.App via an added using.
All 104 v2 tests remain green.
