AADSTS700016 came from the register flow sending the configured
Oidc:ClientId (still a placeholder) as the auth client. The desktop
reference app never needs config: it bootstraps with the first-party
"Microsoft Graph Command Line Tools" public client (14d82eec-...) via
MSAL interactive, which exists in every tenant.
Replicate that for the web app. A server can't do MSAL loopback and the
bootstrap client's redirect URIs don't include /connect/callback, so use
the OAuth 2.0 device authorization grant instead — the web-equivalent of
the desktop interactive flow:
- Add EntraDeviceCodeFlow: POST /devicecode then poll /token with the
bootstrap client. No backing app, no client id/secret, no redirect URI.
- Profiles "Register in Entra" now shows the verification URL + user code
and polls until the admin signs in, then calls AppRegistrationService
to create the per-client app and adopts its appId.
- Remove the dead /connect/register-initiate endpoint and the
IsRegistration branch from the callback (connect flow only now).
The client-tenant register/connect flows are now fully secretless. The
Oidc:* config is used only by the toolbox's own sign-in (unchanged).

- Add missing modal CSS (.modal-overlay/.modal-dialog/.modal-header):
the "Connect to Microsoft" auth modal was rendering unstyled inline
at the bottom of the page. Now a centered dialog with backdrop.
- Surface OAuth connect errors in the modal instead of silently
reopening it with no explanation.
- MainLayout: implement IDisposable so event handlers are actually
unsubscribed (Dispose existed but was never invoked).
- Wire up the Settings theme selector (was a dead control): drop the
unsupported Dark option, call sptb.setTheme on save and on load,
resolve System via prefers-color-scheme.
- Add branded 404 page via UseStatusCodePagesWithReExecute + Routes
<NotFound> (blank white page before).
- Add .progress-fill.indeterminate animation and .progress-panel.
- Home: replace inline JS hover handlers with a .feature-card CSS class.
- Define missing --surface-2 variable referenced by MainLayout.
