Add self-service API tokens (PATs) — the UI had no way to create one

jump-host had zero API-token support: no model, no route, no UI, and
Auth.checkApiToken was explicitly absent from the createOidcClient() call
(per the comment it left behind). proxy and sso-manager-node both have
this; jump-host didn't.

Ports proxy's models/api_token.js + routes/api_token.js pattern (jmp_
prefix instead of prx_), wires checkApiToken into createOidcClient(), adds
Bearer-token support to middleware/auth.js, and adds a token management
card to dashboard.ejs (create/list/rotate/revoke) using app.modal/
app.messages.

Scope note: a jump-host token carries no group claims (unlike proxy's,
which snapshots the creator's groups), so it authenticates as its creator
for non-admin routes (e.g. GET /api/user/hosts) but can never pass
requireAdmin — a deliberate, conservative default rather than recomputing
live admin status per-request.
