A keyless internal user signing in to the Admin UI was redirected off the
post-login landing to /ui/connect, which renders nothing but the MCP apps panel,
so a plain gateway sign-in ended on an MCP OAuth surface the user never asked
for. The landing now renders the keys dashboard for every role. The key lookup
that existed only to make that routing decision goes with it, along with the
useKeys enabled flag it was the sole caller of and the role-hydration hold that
guarded its one-frame dashboard flash
The gateway DCR consent flow moves the other way. Its /authorize handed the
browser to /ui/chat/integrations, whose layout hard-blocks when enable_chat_ui
is off, which is the default, and client-side redirects to /ui/ without the
query string; that destroys the connect_flow handle and strands the MCP client
until the 600s flow cookie expires. It now lands on /ui/connect, which reads
connect_flow and connect_client, mounts the consent banner and puts the apps
panel in connect mode. /ui/chat/integrations keeps its connect-mode handling
this release so flows sealed before the deploy still finish
