Gate period filter behind ?q=v2, limit sorting to Last Seen only

[sarupbanskota]

Summary

• Duration dropdown only renders when ?q=v2 is in the URL (hidden while we debug time-filtered counts)
• Removed sorting from all columns except Last Seen
• Default sort restored to original behavior: attempts desc, then last seen desc, then joined desc
• Last Seen sort toggles: desc -> asc -> back to default

Test plan

• npx ember test --filter="manage-team-members" — 3/3 pass
• Without ?q=v2: no dropdown visible, only Last Seen column is clickable for sorting
• With ?q=v2: dropdown appears and functions
