feat: move unfinished tickets between releases

- Bulk editing gets «Release…» (open releases or none), and the list
  view a release filter, also reachable from each release («Ver en la
  lista», ?release=).
- Archiving a release asks where its unfinished tickets go, as closing
  a sprint does: ReleaseArchivedEvent carries `moveTo` (an open release
  of the same project, or none) and the saga moves them there; finished
  ones stay. In GraphQL, REST and the MCP's archive_release.
- Chapter 10 lists the next features and the ideas to weigh.
