v0.8.27

The live relay follows the bridge's session cap

• Fix: the integration's live relay ended every session after 125 seconds, on
  the JPEG path and on the WebRTC path, whatever the bridge's cap for the
  camera. With live_max_seconds_mains set, a camera without a battery value
  lost its Home Assistant viewer at about 125 seconds, the bridge saw
  no_viewers and ended the session long before its own bound. Reported on
  #94 with bridge 0.8.22 and integration 0.8.26 on a mains powered T8425
  behind a HomeBase 3: two attempts ended at 125.0 seconds with no_viewers
  and session_end, without camera_timeout, while /v1/state reported
  live_max_seconds_mains: 1800.
• The relay now bounds itself by the bridge's cap for that camera plus five
  seconds: 125 seconds for a battery camera or a camera missing from the
  inventory, and live_max_seconds_mains plus five seconds for a camera the
  inventory reports without a battery value. The state's
  live_max_seconds_mains is validated at the boundary as a whole number from
  120 to 3600, and a bridge before 0.8.22 that does not report it keeps 120.
  The bridge still ends the session at its cap and closes the socket. HA's
  bound only catches a bridge socket that neither sends nor closes.
• Nothing else changes: the 10-second lease, the 20-second startup timeout,
  the card's no-restart rule and the per-HomeBase limit are unchanged. The
  bridge stays at 0.8.22.

Upgrade and rollback

Update the integration to 0.8.27 and restart Home Assistant, then refresh the
dashboard. The bridge stays at 0.8.22. To roll back, restore integration
0.8.26 from your backup.

Validation: Integration-only fix of the Home Assistant relay bound, bridge unchanged at 0.8.22. Cause and effect are established by the reporter's diagnostics on #94 with bridge 0.8.22, integration 0.8.26 and a mains powered T8425 behind a HomeBase 3: two sessions ended at 125.0 s with no_viewers and session_end, without camera_timeout, while /v1/state reported live_max_seconds_mains 1800, matching the fixed 125-second relay timeout that both relay paths carried. Unit tests cover the state parsing, the per-camera rule and a relay that ends at its own bound on both transports (254 tests, 96.9 percent coverage). Installed on the maintainer's HA OS bench (integration 0.8.27 with bridge 0.8.21, battery cameras): the integration loads, serves the 0.8.27 card and shows no errors. No device command, media or bridge behaviour changed, so no new physical test was run. The 30 to 60 minute observation on a mains powered camera on #94 follows this release.
