no issue
- move members loading code into `members` controller so that it's more accessible to other areas of the app
- add `refreshData()` to the `members` controller which forces members list and stats to be re-fetched
- call `members.refreshData()` after successful upload of members import file
- store range/days in `membersStats` service so that it's remembered across refreshes and component renders
no issue
- ran [`ember-native-class-codemod`](https://github.com/ember-codemods/ember-native-class-codemod) on members-related files
- updated files to remove need for `@classic` decorator where possible
- switched to tracked properties
- removed usage of `this.get/set/toggleProperty` etc
- swapped usage of `{{action 'foo'}}` for `{{this.foo}}`
