fix(site/src/pages): use RotateCcwIcon for update actions (#28183)

Closes
[DES-22067](https://linear.app/codercom/issue/DES-22067/update-and-restart-action-uses-a-cloud-icon).

The "Update and restart" / "Update and start" actions used `CloudIcon`,
which reads as a cloud/network concept instead of an update-and-restart
build action.

Switch them to `RotateCcwIcon`, which the UI already uses for:

- the `Restart` button on the workspace page
- the `Update` action in `WorkspaceOutdatedTooltip`,
`AgentOutdatedTooltip`, and `SubAgentOutdatedTooltip`

Call sites changed:

- `WorkspacePage/WorkspaceActions/Buttons.tsx` - `UpdateButton`
- `WorkspacesPage/WorkspacesTable.tsx` - "Update and start workspace"
and "Update and restart workspace" primary actions
- `WorkspacesPage/WorkspacesPageView.tsx` - batch "Update" menu item

The `requireActiveVersion` variant still uses `PlayIcon`, since that
path starts the workspace on the active version rather than offering a
choice. Worth a separate design pass if that should change too.

<summary>Investigation notes</summary>

Verified against `origin/main` (`af90d8e2be`): no prior PR referenced
DES-22067 and all three `CloudIcon` usages were still present. `grep`
confirms no `CloudIcon` usages remain in `site/src` after this change.

Icon conventions found in the codebase:

- `RotateCcwIcon`: restart, update (outdated tooltips), retry
(RetryButton, TasksTable, TaskPage, HealthLayout)
- `RefreshCwIcon` / `RefreshCcwIcon`: softer "reload data" flows
(terminal, secrets, prebuilds invalidate, inbox, git panel)

`data-testid="bulk-action-update"` is preserved on the batch update
item, so e2e coverage is unaffected.
