Bump uiprotect to 15.4.2

Proposed change

Bumps uiprotect from 15.4.1 to 15.4.2.

15.4.2 fixes the public integration websocket keepalive: it emits CONNECTED as soon as the connection is established (instead of only after the first data frame), and sets an aiohttp heartbeat on the two public websockets. This keeps upstream reads flowing so the UniFi OS nginx reverse proxy's proxy_read_timeout 10m no longer idle-drops the quiet subscribe/devices channel — which was making the Alarm Manager and other public-API entities go unavailable ~10 minutes after arm/disarm on low-traffic setups.

Changelog: v15.4.1...v15.4.2 (uilibs/uiprotect#1071).

Pull request overview

This PR bumps the uiprotect library from 15.4.1 to 15.4.2 for the UniFi Protect integration. The new release (published 2026-07-05, containing uilibs/uiprotect#1071) fixes the public integration websocket keepalive so the UniFi OS nginx reverse proxy no longer idle-drops the quiet subscribe/devices channel. This resolves the reported issue (#175610) where the Alarm Manager and other public-API entities went unavailable ~10 minutes after arm/disarm on low-traffic setups, since those entities' availability is tied to last_public_update_success / the public devices websocket health.

Changes:

• Bump uiprotect pin to 15.4.2 in the integration manifest.
• Regenerate the corresponding pin in requirements_all.txt.
