Expandable process groups in the Processes tab

[Danil-Didkovskiy]

Grouped rows in the Processes tab now have an inline expand chevron. Clicking it reveals the group's member processes indented beneath the row, ranked by the active metric.

Pull request overview

Adds inline expand/collapse for grouped rows in the Processes tab, showing member processes indented under the group and keeping list/member ordering stable during pointer/keyboard interactions.

Changes:

• Introduces a generic order-pinning utility (pinOrder) plus a reusable React hook (useOrderPin) for pinned lists (groups, detail members, inline expanded children).
• Adds inline disclosure UI to grouped process rows and factors member rendering into a shared MemberRow component; centralizes member ranking via rankMembers.
• Tightens process-action disabling to treat MoStats direct child helpers as “self” and hardens formatStartTime against out-of-range dates.

• Using only pid as the React key can cause incorrect component reuse if a PID is recycled while the detail view is open. DetailMember includes startedAtUnixMs; incorporate it into the key to avoid collisions across process lifetimes.

          {members.map((member) => (
            <li key={member.pid}>
              <MemberRow member={member} onOpen={onOpenMember} />
            </li>
