fix(pine): bump Home Assistant to 2026.7.3 — satellite keepalive support

HA 2024.1's Wyoming integration predates ping/pong keepalives. The PineVoice
satellite firmware (wyoming 1.7.2) drops connections idle for ~8s, so HA
looped on 'Satellite disconnected' forever and the speaker never worked.
HA 2026.7.3 pings satellites and holds the connection (verified on
framework-pt: link stays ESTABLISHED, wake word reaches Assist).

Catalog regenerated with the bump — needs the signing ceremony before the
origin publish.
