0.2.35: exited positions show history clipped at the exit date

The eNAV keeps producing statements after an exit (quarterly for funds,
event-driven for SPVs), so an unfiltered graph would crash to zero.
Now the exited card gets its collapsible History back — chart + table
showing the capital journey up to exited_on only. Post-exit statements
stay recorded (audit trail; Undo restores full history) but are never
plotted. History section extracted into a shared HistorySection
component; toggle counts "statements" not "quarters" (SPV statements
are event-driven).
