* refactor(ui): extract auth state into AuthContext
Move auth state (token, userID, userRole, accessToken, premiumUser, userEmail,
disabledPersonalKeyCreation, showSSOBanner) out of src/app/page.tsx into a
new AuthProvider at src/contexts/AuthContext.tsx. Wrapped at the root layout
so login/onboarding/dashboard routes all have access via useAuth().
Day 1 foundation for the App Router migration: migrated (dashboard)/X/page.tsx
route entry points won't have a parent passing props, so shared auth state
must live in a context they can read from.
Sub-components are unchanged — they still receive accessToken/userID/userRole
as props from page.tsx (which now reads them from useAuth()). Only the
page.tsx → top-level-page-component handoff is de-drilled; deeper prop
drilling is left for the per-page migration to address.
Net change: -86 lines from page.tsx (state + two effects moved), +5 in
layout.tsx (provider wrap), new AuthContext.tsx (~140 lines), test update
to wrap CreateKeyPage in AuthProvider.

* fix(ui): await getUiConfig before clearing authLoading
The AuthContext refactor flipped authLoading to false synchronously on mount
while letting getUiConfig() run fire-and-forget. On SERVER_ROOT_PATH deployments
this races the unauthenticated login-redirect effect: the redirect fires with
proxyBaseUrl still at its module-init value, sending users to /ui/login instead
of {SERVER_ROOT_PATH}/ui/login.
Restores the original sequencing inside AuthProvider's mount effect and adds a
Playwright spec wired into the existing SERVER_ROOT_PATH workflow matrix. The
spec delays the config endpoint via page.route() to make the race deterministic
across CI runners.
