Remove broken total count from workflow version

[thomtrp]

Problem

Opening a workflow run with a form step in the side panel, closing the form and reopening it crashes the app: <SidePanelWorkflowStepInfo> blows up on workflow.versions.find because versions is null in the Apollo cache.

Root cause

useWorkflowVersion was selecting:

workflow: { id, name, statuses, versions: { totalCount: true } }

Twenty's GraphQL field generator doesn't support connection-level scalars — { totalCount: true } is interpreted as fields on the inner WorkflowVersion node, gets filtered out, and the query collapses to:
versions { edges { node { __typename } } }
The server returns versions: null for that empty-node selection.

Why now
The selection has always been wrong, but two recent changes made it consistently surface:

Apollo Client v4 upgrade (#18584): stricter normalized writes, null always wins.
#20242: WorkflowRunSSESubscribeEffect in the form filler keeps SSE flowing, which re-fires useWorkflowVersion more often, making the bad query consistently the last writer.
