Support 11pm close times

[sotm-ross]

Why?

While working on a project where I needed to provide our hours in UTC times, I noticed a bug with 11pm closing times where an hour would be "eaten" by business_hours.after(time) if time was right up against the end of the work day/11pm:

BusinessTime::Config.beginning_of_workday = "2pm"
BusinessTime::Config.end_of_workday = "11pm"
# standard Mon-Friday work week

monday = Time.parse("2024/09/30 9:00pm")
tuesday = Time.parse("2024/10/01 4:00pm")
4.business_hours.before(tuesday) == monday # true
4.business_hours.after(monday) == tuesday # false

Strangely, the reverse problem didn't exist. 4.business_hours.before(<Tues@4pm>) accurately returned Mon@9pm.

What?

• Refactor calculate_after:
  • Instead of defaulting to Time.roll_forward(after_time) when after_time is 00:00:00, use the logic for checking if
    after_time is outside of work hours instead so that the delta isn't lost.
  • That introduced a bug with the exceptions in place for closing times of 00:00:00, so I also added a check to ignore the delta if it was only 1 second.'
• match the pattern in calculate_before for simplicity.
