refactor: migrate from custom config system to Statamic addon settings

Remove custom YAML-based configuration system and replace with
Statamic's built-in addon settings. Delete settings.yaml,
ConfigController, and Config model. Simplify HasConfig trait to use
Addon::get()->settings() instead of custom file-based configuration.

refactor: replace custom config routes with settings blueprint

feat: add comprehensive settings blueprint with property ID, date range, and widget configuration options

fix: update analytics route from google-analytics to isapp-analytics for consistency

style: adjust declare statement spacing to match coding standards
