Project Settings Rebuilt Around Members and Invitations

What's changed

• Open Project Settings from the project menu: General holds the project name (only the owner can change it), your primary project, API access and, last, Delete project, and Members lists everyone who can reach the project
• The Members tab lists the owner first and then every other member with their role and the date they joined; a project nobody else had joined used to say it had no members, because the owner was missing from the list
• Click a member to open a drawer: the owner can change their role or remove them, a member can leave from their own row, and changing a role asks you to confirm it's you
• Invite member opens a drawer for the email address and a role (Administrator or Editor), and Pending invitations lists every invitation still waiting, each with Cancel behind a confirmation
• A removal, leave or delete that is refused now says why in its dialog; before, the refusal was not shown
• Delete project lists what stands in the way (resources to delete first, money owed, linked billing organizations, or a primary project) beside a disabled button, and asks you to type the project name before it deletes
