- New get_sidecar_config.md for GET /api/devices/:id/sidecar and
/sidecar/download: the .bookhoard.json config served to devices
(endpoints, books keyed by per-format SHA-256 with UUID fallback,
collections, format availability) used by the KOReader plugin to
self-configure
- register_device.md: correct the response — no device_id at
registration; auth_url is /devices/approve/:id (was the nonexistent
/devices/auth/confirm/:id); document poll_interval and
setup_instructions, and the approve-then-poll flow
- get_devices.md: fix the status endpoint path to
POST /api/devices/register/status (was /api/devices/auth/status)
