Misleading 'Escalation' ticket attribute name in SLAs, Scheduler and Trigger should be named 'Escalation_at'

[MrGeneration]

Infos:

• Used Zammad version: 3.0
• Installation method (source, package, ..): any
• Operating system: any
• Database + version: any
• Elasticsearch version: any
• Browser + version: any

Desiredbehavior:

We should rename the condition "escalation" to "escalation at".
The current naming is miss leading, as it suggest that this will check if a ticket has escalated.

Infact, this triggers on every moment, when your "escalation_at" field changes.
The function itself works as designed.

I indeed spent some hours trying to understand the "escalation" trigger, and this request for renaming is probably a very nice idea.

While this could seem abvious for a zammad dev, some users (like me) just get lost.

(i also spent time looking at API, so i know the escalation_at variable)
