Update how member filters work

Background

In &11023 we are working on listing members of shared groups. Currently the filters don't work for shared members. If you apply a filter then no shared members are listed. There was discussion about this in #429341 (comment 1619448597)

Proposal

Related discussion - #429341 (comment 1785271203)

Update filters to work as described below:

• No filters
  • All members show including members from shared groups
• Direct filter
  • Members directly invited to a group/project
• Indirect filter
  • Members inherited from a parent group
  • Members from from shared group

Implementation plan

Backend

Needs refinement. Looks like app/controllers/concerns/membership_actions.rb#L148-162 is responsible for filters

Frontend

Ping @peterhegman if you need frontend support

1. Update options title property in app/assets/javascripts/members/constants.js#L142 to Direct and Indirect. value property should match what is used in the backend.
