chore: clean up trailing whitespace and formatting

- Removed unnecessary leading and trailing blank lines in several
  ActiveAdmin register files.
- Reformatted string delimiters for consistency, changing single quotes
to double quotes in tracking events in the Cities and WeatherArts
controllers.
- Ensured proper spacing in array definitions across several
  models, including Ahoy::Event and Ahoy::Visit.

These changes improve code readability and maintain consistency
throughout the codebase by ensuring uniform use of quotes and
removing excess whitespace.
