fix(web): the ticket page shows its own changes at once, and a tidier header

The ticket page only refreshed when the live update arrived; a dropped or
slow socket left an edit, a new subtask or a comment unseen until the
page was reloaded. After each change made there, it now asks for the
ticket, its comments and its subtasks again (twice, since the API
projects its read model a moment after answering).

"Seguir" and "Editar" are two matching buttons, side by side and level
with the title's first line (under it on narrow screens), instead of a
large button with a stray arrow and a loose grey pencil.
