Kamron Batman bf31bceea4 refactor(spawners): Approach A→B swap — deserialize via SpawnerDto records (atomic)
Replace the shadow-property (Approach A) JSON mechanism with plain DTO records
so malformed files fail as GC-only and never leak live world Items.

Changes:
- Add Json/SpawnerDto.cs: abstract SpawnerDto + SpawnerDataDto / RegionSpawnerDto /
  ProximitySpawnerDto, each [JsonDiscoverableType("<name>")] with ToSpawner()
- Add BaseSpawner.Dto.cs: internal ApplyDto(SpawnerDto) + private-protected Dto*
  export helpers (DtoGuid, DtoMinDelay, etc.)
- Add Spawner.Dto.cs, RegionSpawner.Dto.cs, ProximitySpawner.Dto.cs: ToDto() overrides
- Add public abstract SpawnerDto ToDto() to BaseSpawner
- Retarget SpawnerJsonSerializer: discovery filter BaseSpawner→SpawnerDto; polymorphism
  gate typeof(SpawnerDto); remove PruneToJsonProperties + AddOnDeserialized modifiers
- Delete BaseSpawner.Json.cs, Spawner.Json.cs, RegionSpawner.Json.cs,
  ProximitySpawner.Json.cs (Approach A shadow-property partials)
- Remove [JsonDiscoverableType] + [JsonConstructor] from Spawner/RegionSpawner/ProximitySpawner
- Rewire ExportSpawnersCommand: build List<SpawnerDto> via spawner.ToDto()
- Rewire ImportSpawnersCommand: Deserialize<List<SpawnerDto>> then dto.ToSpawner();
  map-null check now fires before ToSpawner(), so no orphan Items on bad map
- Delete 3 Approach-A round-trip tests; add SpawnerDtoRoundTripTests (4 cases)
- Update ExportImportFileTests + LegacyHomeRangeTests to use DTO path
- Add Import_MalformedFile_LeaksNoWorldItems to ImportCleanupTests

Build: dotnet build ModernUO.slnx → 0 errors, 0 warnings
Tests: dotnet test UOContent.Tests → 478/478 pass
