fix: extend timeout for schematic query commands on large files

Add list_schematic_nets, list_schematic_labels, and get_schematic_view
to the longRunningCommands list so they use the 10-minute timeout
instead of the default 30 seconds. These commands regularly exceed
the 30s limit on larger schematic files.
