Dylan/fix/csharp module scheduling repeating

[dylanh724]

About

• Better, more-clear, more-realistic scheduler example
• Split up the autogen codeblock result
• Added a repeated scheduler example
• Normalized consistency for DbEventArgs arg name (named dbEvent; same as the new Unity demo)
• Added a warning for Exceptions not logging (known bug in the C# SDK). Discussion: https://discord.com/channels/931210784011321394/1220579367462113351

Why?

Scheduling was a confusing subject that got me earlier - and is vastly different from Rust's way of scheduling. I also initially created repeated schedulers wrong, where the current docs don't discuss or example repeated.
