Bohan Jiang 37d9fafda6 feat(issues): add Remove parent issue action (MUL-3764) (#4630)
* feat(issues): add Remove parent issue action to promote a sub-issue to standalone (MUL-3764)

Surfaces a discoverable UI affordance for clearing an issue's parent — the
backend and CLI (multica issue update --parent "") already support it, but
the Official App only exposed Set parent. Adds:

- A 'Remove parent issue' item in the issue actions menu (dropdown +
  right-click), shown only when the issue has a parent.
- A hover unlink button on the parent card in the issue detail sidebar.
- A removeParent handler that clears parent_issue_id and stage in one
  write (stage only orders sub-issues under a parent) with a success toast.

Closes #4629

* fix(issues): toast remove-parent on success only, prune old parent's children cache (MUL-3764)

Addresses review feedback on #4630:

- use-issue-actions.ts: the remove-parent success toast fired eagerly after
  mutate(), so a request that failed on permission/network/validation would
  flash "removed" before the error toast and optimistic rollback. Move it to
  onSuccess so only a server-confirmed detach is announced.

- mutations.ts: when a write re-parents an issue away from its current parent,
  prune it from the old parent's children cache instead of patching it to
  parent_issue_id: null in place. The parent's sub-issues list renders that
  array directly, so the orphaned row used to linger until the settle refetch.
  onError still restores prevChildren, so the prune rolls back on failure.

Adds cache-prune coverage (optimistic remove / rollback / non-reparenting
no-op) and onSuccess-vs-onError toast coverage.
