Adds project 43 as a child of project 10 so tests can exercise the
"inherited Write via parent" path exploited by GHSA-2vq4-854f-5c72.
User 1 has Write on project 10 via users_projects id=4 and therefore
inherits Write on this child via the permission CTE.
Resolves#2490. Users with team access on a parent project were not seeing
subtask relations for tasks in child projects because getUserProjectsStatement
does not walk the project hierarchy. The fix wraps the base query in a
recursive CTE that traverses child projects via parent_project_id.
CheckIsArchived() previously skipped checking a child project's own
IsArchived flag when ParentProjectID > 0, immediately recursing to
only check the parent. This allowed write operations on individually
archived child projects whose parent was not archived.
Now the function loads the project from the database first, checks its
own IsArchived flag, and only then recurses to check parent projects.
As I mentioned [here](https://kolaente.dev/vikunja/api/pulls/1442#issuecomment-55215), this is mainly a cleanup of @zewaren 's original [PR](https://kolaente.dev/vikunja/api/pulls/1442).
It adds support for the `RELATED-TO` property in CalDAV's `VTODO` and the `RELTYPE=PARENT` and `RELTYPE=CHILD` relationships. In other words, it allows for `ParentTask->SubTask` relations to be handled supported through CalDAV.
In addition to the included tests, this has been tested by both @zewaren & myself with DAVx5 & Tasks (Android) and it's been working great.
