chore: improve sign layout ticking

[derklaro]

Motivation

The current sign layout ticking process is based on the assumption that there won't be any race conditions. However, there is a slim chance that a race happens which will then cause all layouts of a holder to freeze until a server restart or config reload.

Modification

Base the sign ticking process and layout retrieval entirely on the last tick when the sign was updated. This removes the need for different places to lock/unlock sign layout ticking and therefore prevents races between the sign ticking thread and the main server thread. This also applies to the map that tracks the layouts that need to be updated as a result of the current tick.

Result

Sign layout ticking is resistent against race conditions and uses the server tick count as the single point of truth when retrieving the applicable sign layout.
