The Configuration table listed ClientConnect__RedirectUri (/connect/callback)
alongside the Oidc__* settings, implying it was an OIDC sign-in redirect URI on
the toolbox's own Entra app. It isn't: /connect/callback is the per-profile
SharePoint connect flow (PKCE public client using each profile's own ClientId),
registered on the client-tenant apps — not the sign-in app.
Split the two flows out explicitly: /signin-oidc on the sign-in (Web) app,
/connect/callback on each profile's (public client) app. Also document that the
confidential sign-in app needs an HTTPS redirect URI (http only for localhost),
so a plain-HTTP LAN deployment needs an HTTPS-terminating proxy or must fall
back to local login.
