Port the shared otm-login/otm-menu CSS+markup from
@otm/account-panel otm-login-core.ts 0.44.0 (verbatim, kept in sync
via header comments) into login.html and the sidebar account menu in
index.html/app.js. Accent is the studio's --plum, heading font via
the module's --otm-font-display variable. Behaviour is unchanged
(OTM-first / "Other ways to sign in" toggle, server-filled
__OTM_SSO_URL__, same reasons).
The account menu needs to know whether a session came in via OTM to
show the badge/"Manage OTM account" link, which the session didn't
track before — added a `via: "otm"` claim on the SSO callback's
session and exposed it from GET /api/me (additive; password and
operator-magic sessions are unaffected and read as not-linked).
