A very long asset duration no longer crashes the viewer

Typing a very large duration to keep an asset on screen forever, such as 9999999999999 seconds, made the viewer crash when that asset came up, and crash again after every restart while the asset stayed in the schedule.

From Anthias 2026.07.1, a duration can be at most 31,536,000 seconds, which is 1 year:

• In the web interface, a longer duration is saved as 1 year. The same goes for "Default duration (seconds)" and "Default streaming duration (seconds)" in Settings.
• The API, from v1 to v2, answers a duration below 0 or above 31,536,000 with a 400 response, when creating or updating an asset. On v2 the same limit applies to default_duration and default_streaming_duration in the device settings.
• A video file that reports an impossibly long length is given 1 year instead.
• An asset saved with a longer duration before you upgrade plays for 1 year at most instead of crashing the viewer.
