- added `{{members-event-filter}}` helper that can be used to build an event filter string that will always exclude email events when the newsletter is disabled
- useful when used in conjunction with `{{members-event-fetcher}}` because the filter is automatically adjusted for you without needing additional logic or JS backing files for components
- updated dashboard and member screen activity widgets to use `{{members-event-filter}}`
- updated members-activity screen
- updated to use `{{members-activity-filter}}` helper in the template which allowed for removal of filter generation in the controller
- changed `@hideMemberOnlyEvents` to `@hiddenEvents` on `<MembersActivity::EventTypeFilter>` so that we can control which events are available in the filter based on newsletter enable/disable and presence of a filtered member

- renamed `@updateExcludedEvents` to `@onChange` and updated associated action name so we have consistent naming for our select-like components
- added `<MembersActivity::MemberFilter>` component
- utilises `<PowerSelect>` with a custom trigger component and and a debounced search via the member's API
- does not use `<PowerSelect>`'s default "selected" behaviour in favor of replacing the select with a button to provide a clearer "reset filter" UX that's easier to build/style outside of the power-select components
- added `.ember-power-select-trigger-reset` class to reset margins, paddings, borders, and heights so that it's easier for a custom trigger's contents to control the display

- extracted member details display into a `<GhMemberDetails>` component for re-use in the member details and members-activity screens
- added loading of member record from the member id query param and displayed the member details above the table when a member filter is present
- hid the member column in the events table when a member filter is present
- it's useless/repeated info at that point
refs https://github.com/TryGhost/Team/issues/1277
- added `member` query param that expects a member ID
- using an ID as it makes the filtering simpler than using an email because there is no async member fetching required
- updated `filter` generation to build `type` and `member` parts and combine them in an AND query
- updated link in member screen to use a `member` param rather than a `filter` param
- resets any `excludedEvents` param so all events for the member will be shown when following link from member->members-activity
refs https://github.com/TryGhost/Team/issues/1277
- we were inadvertently adding an empty string to the excluded events set resulting in a trailing comma in the filter string (`type:-[x,y,z,]`)
refs https://github.com/TryGhost/Team/issues/1290
- changed query param from `filter` to `excludedEvents`
- exposing filter directly creates problems converting back to NQL after parsing+modifying the query
- removes suggestion that raw NQL can be manipulated by editing the URL
- allows us to use a set of well-defined query params to build the underlying filter string from scratch each time a query param changes
- added `<MemberActivity::EventTypeFilter>` that renders a filter button with a dropdown containing a checkbox for each event type
- if no `member` property is set on the members-activity controller (soon to be another query param) any email event types are hidden because the API can't currently paginate those correctly and in any case they would drown out any other type of event
refs https://github.com/TryGhost/Team/issues/1277
- added `/members-activity` route with associated controller, template, and components behind labs flag
- table component currently renders some dummy rows
- added navigation item to main menu
- will use the currently set `?filter` query param unless clicked whilst already on the `/members-activity` screen in which case it will reset the query
- added link to dashboard members activity panel
- added link to member details activity panel
- sets the filter param to `?filter=member:{member.id}` in preparation for the feed to be filtered to the member's activity
- updated the labs-flag test helper file to export both `enableLabsFlag()` and the new `disableLabsFlag()` so it's easier to test for flag-disabled functionality
