Subject: [PATCH] feat(client): migrate ItemNumberFilterPanel to API clients

Update ItemNumberFilterPanel.razor to use ILookupApiClient and IFileApiClient
instead of legacy ILookupService and IFileService interfaces. All methods now
use the result.Switch() pattern for proper ApiResult error handling.
