fix(cleanup): admin delegation bypass, ORI lifecycle gate, dead try/catch, find() named args (M1-M4)

[rubenvdlinde]

Summary

• M1 DelegationController revoke/expire: add IGroupManager; admins pass null (skip ownership check), non-admins pass callerUid. Admins can now manage any delegation without triggering the principal-ownership error.
• M2 OriController::show: lifecycle gate changed to null-check — schemas without lifecycle/status fields (votes, persons, etc.) were always returning 404 because empty string != 'published'. Now only blocks when the field is actually present.
• M3 OriPublicationService::publish: rethrow after logging so VotingService outer catch can attach oriPublicationError to round data. Previously swallowed all exceptions, making the outer catch dead code.
• M4 Standardize find() to named-arg pattern (id/register/schema) in DelegationService, TaskService, MotionCoauthorService. Removes redundant setRegister/setSchema prefix calls.
• L2 Already resolved by PR A (AgendaController requireChairOrAdmin no longer uses findAll with register/schema in filters[]).
• L3 Already present in MailReplyHandler::signMailEntry (@SPEC annotation exists at line 167).
• Fix Application.php DI: add groupManager to DelegationController wiring.

Test plan

• PHPCS: clean (0 errors)
• PHPStan: clean (0 errors)
• Admin can revoke/expire any delegation (no 403)
• Non-admin can only revoke/expire their own delegation
• ORI /votes/{id} returns 200 for valid vote objects (not 404)
• VotingService closeVotingRound attaches oriPublicationError when ORI publish fails
• DelegationService/TaskService/MotionCoauthorService find calls use named-arg form
