feat(web): English paths, and a portfolio that updates itself

/cartera, /explorar and /p/:key/proponer are /portfolio, /explore and
/p/:key/propose now, like every other path; the Spanish ones redirect,
so links already shared keep working. Settings sections go by
?section= with English names.

The portfolio reads itself again, quietly, when a ticket, sprint or
release of the projects shown changes, when my projects change, or when
the live connection comes back; «En directo» replaces the refresh
button.
