fix(bridge): strip duplicate /api prefix in BaserowClient base URL

BASEROW_API_URL is http://baserow:80/api and every BaserowClient path is
written with an /api/... prefix, producing http://baserow:80/api/api/...
-> Baserow 404 on all /views/:id/data and /views/table/:id calls (admin
client was unaffected: its paths omit /api). Normalize the base to
host-only so the /api/... paths resolve correctly.
