fix(defaultRouteInit): pass sorted display sets to hanging protocol for deterministic viewport order (#5933)

fix: pass sorted display sets to hanging protocol for deterministic viewport order

The `applyHangingProtocol` function already sorts display sets by modality
priority and series number into `sortedDisplaySets`, but the unsorted
`displaySets` array was being passed to `hangingProtocolService.run()`.

This caused non-deterministic viewport ordering across page loads because
`displaySetService.getActiveDisplaySets()` returns display sets in creation
order, which depends on asynchronous network responses.
