0.2.33: exited positions (secondary-sale edge case)

A member who sold/transferred their stake showed a phantom -100% loss
($0 ending balance, no distribution through the fund). Now:
- entity_access.exited_on (migration e1f2a3b4c5d6), set/cleared from the
  Partners tab (writer-only, inline date picker, audited)
- LP portal card shows a quiet "Exited <date>" badge, keeps documents,
  hides balance/gain
- portfolio summary excludes exited positions ("Excludes N exited")
- fund committed totals (rollup + Partners tab) skip exited members so
  seller + buyer are not double-counted
