fix(workflow): rename the trigger step through the dedicated mutation (#23450)

## Bug

Renaming the **trigger** step from the workflow side panel fails with:

> Updating a workflowVersion through the generic mutation is restricted.
steps, trigger, status, position, workflowId and coreWorkflowVersionId
cannot be changed...

Renaming a **regular** step works, which is why this is easy to miss:
only the trigger branch is broken.

## Cause

This is a regression from #23207. That PR added the server-side denylist
on `updateOneWorkflowVersion` and switched
`useUpdateWorkflowVersionTrigger` to the dedicated
`updateWorkflowVersionTrigger` mutation, but missed the call site in
`SidePanelWorkflowStepInfo`, which still did:

```ts
if (isTrigger) {
  await updateOneWorkflowVersion({          // generic mutation, sends `trigger`
    updateOneRecordInput: { trigger: { ...stepDefinition.definition, name: title } },
  });
} else {
  await updateWorkflowVersionStep({ ... }); // dedicated, unaffected
}
```

The observed request confirms it: `UpdateOneWorkflowVersion` with
`input.trigger`.

## Fix

Route the trigger branch through `updateTrigger`, which already resolves
the draft version, calls the dedicated mutation, marks the step for
recomputation and updates the cache.

`useUpdateWorkflowVersionTrigger` now accepts an **optional**
`instanceId`. This matters here: the side panel computes the visualizer
instance id explicitly (it already passes it to
`useGetUpdatableWorkflowVersionOrThrow`), and without it the hook would
resolve the updatable version from a different component instance. Being
optional, the four existing callers are unaffected.

Also removes the now-redundant `getUpdatableWorkflowVersion()` call on
the trigger path, so a rename no longer risks resolving the draft twice.

## Verification

- `nx typecheck twenty-front` green
- `oxfmt` + `oxlint --type-aware` green on both changed files
- `useUpdateWorkflowVersionTrigger` unit tests green (2/2)
- Not yet clicked through locally; the reporter hit this on a dev
instance and can confirm the rename now succeeds
