feat: portfolio of all my projects

/cartera (and GraphQL portfolio, REST /api/me/portfolio, MCP
get_portfolio) shows every active project I belong to (not archived, not
as a guest) at a glance: open, overdue, blocked and stuck tickets, the
sprint under way and whether it gets there, planned releases with their
forecast, and the open epics with their progress. It reuses the
dashboard's computations. A release with no tickets now reads «Sin
tickets» instead of «Todo hecho», here and on the dashboard.
