The mentor list now ends with a Teams column showing chips of each
mentor's active assignments (truncated at 2 + overflow badge). Clicking
any row opens a right-side Sheet with the mentor's profile (expertise,
country, joined date, max assignments) and a per-team activity feed —
project, status (active / completed / dropped), assignment date, and
counts of messages / files / milestones with their last timestamp.
Stat cards on both the Mentor and Mentee panels were stale and not
particularly informative, so they're gone — the table itself is now
the focal element on each panel.
getMentorPool gained an activeTeams[] field; new getMentorDetail query
backs the side sheet.
