feat(home): live updates via Mercure — server pushes device state to the PWA
Subscribe per-device with a Symfony Mercure hub: server publishes a fresh
device payload after every poll (200/304/204), every PATCH, and every
lock/unlock. The frontend opens one EventSource per device topic and
splats inbound JSON straight into the devices store — same shape as
GET /api/devices, so no envelope handling.

Topic: https://pictureframe.edholm.me/devices/{id}

Stack mirrors aqua-iq:
- symfony/mercure-bundle + config/packages/mercure.yaml
- App\Service\MercurePublisher (errors swallowed + logged; a flaky hub
  must not break a poll response)
- App\Service\DeviceSerializer extracted as the single source of truth
  for the wire shape (REST + Mercure share it)
- Frontend useDeviceMercure() composable: opens/closes EventSources to
  match the device list reactively, reconnects on hub-side closes
- SpaController exposes MERCURE_PUBLIC_URL via window.__PF_MERCURE_URL__

Production compose adds a dunglas/mercure container with Traefik labels
for pictureframe.edholm.me/.well-known/mercure (handled separately on
the host since the file isn't in this repo).
