feat: saved views of my work, across my projects

A person saves named views of «my work»: projects, assigned to me, that I
follow, status categories, priorities, bugs only, overdue and text. They
are private (Mongo my_views, no history), listed and deleted by their
owner (GraphQL myViews / saveMyView / deleteMyView, REST /api/me/views),
and run as the cross-project search, which gains project, priority,
bugsOnly and overdue filters (also in MCP my_issues). The home page shows
them as a bar above «my work», with a drawer to save a new one.
