Updates mock event data and adds logging

Updates mock event data to reflect future dates for testing purposes.

Adds console logging in various managers to aid in debugging and understanding the event loading and rendering process.
Specifically, logs the number of loaded events, the first and last event details, and information about event rendering and time axis creation.

Also, adds execution permission for PowerShell scripts in the .claude settings.
