Members Page button enhancements (Admin perspective)

**INTRODUCTION**
As an admin, I want to access all user management actions via a unified dropdown menu, so that the interface feels consistent, professional, and prevents accidental toggling or misuse.

**DESCRIPTION**
The toggle switch for making users active/inactive feels overly playful and is prone to accidental toggling due to its design. To improve usability and ensure all actions are consistent, I propose moving the "Make Active/Inactive" option into a three-dot dropdown menu, placed next to the "Resend Invitation" icon.

This change will consolidate all user management functions (delete user, edit role, make active/inactive) into one unified interface, ensuring clarity and reducing the risk of accidental actions.

Tooltips defined in #527

**ACCEPTANCE CRITERIA**

- Editing roles and changing the active status are limited to super-admins.
- Three-dot menu placement - Add a three-dot icon next to the "Resend Invitation" icon for each user. The three-dot menu should open a dropdown list with the following actions:
- a) Edit Role
- b) Delete User
- c) Make Active/Inactive

- Text for "Make Active/Inactive":
- If the user is active, the dropdown should display: "Make Inactive."
- If the user is inactive, the dropdown should display: "Make Active."

- Resend invitation should appear in the same way, with the same icon as before, and only for users who haven't registered yet, but are invited.

- Ensure the dropdown menu works seamlessly on both desktop and mobile views.
