fix: workspace current / list must honor --workspace override (PLA-1590)

Both commands read the persisted workspace directly via
`f.Config.GetContext().GetWorkspace()`, so a `--workspace foo` override
was silently ignored — `workspace current` reported the persisted
workspace and `workspace list` put `*` on the persisted row, not on
the override. Caught running the Bucket 6 dev-2 E2E:

  $ /tmp/zeabur-dev2 workspace switch team-A
  $ /tmp/zeabur-dev2 --workspace team-B workspace current
  team-A  [...]  team  ...      # wrong — override was team-B

This is the same class of bug as the deploy.go F1 finding from the
panel review: display source must match the resolved source the rest
of the command sees. Switch both commands to `f.CurrentWorkspace()` /
`f.CurrentOwnerID()` so they reflect the effective workspace for the
invocation. Existing `TestFactory_CurrentOwnerID_OverrideBeatsPersisted`
covers the underlying helper; this fix is the consumer side.

Verified on dev-2 against api-2.zeabur.dev:

  $ /tmp/zeabur-dev2 --workspace pla1230 workspace current
  pla1230-probe-...  [69e72943...]  team  Administrator   # ✓

  $ /tmp/zeabur-dev2 --workspace pla1230 workspace list
  *  69e72943...  pla1230-probe-...   team  Administrator # ✓ marker on override
