GUI: add sound effect for day and night switch on upkeep

[JayDi85]

Related to daybound/nightbound mechanic from #8200. Client must play sound after day/night change.

Additional tasks:

• [ ] sound engine can be improved to receive play sound commands from the server (current version compares a battlefield between game updates and play sounds by a diff).

Not sure if this should be a separate issue, but I think it'd be nice to have a day/night emblem show the current day/night value without needing to check the game log.

Added global card hint with day/night hint in 2fa07c8ecc6d9a1cbe45d1029830aa395ca4fba6
