A "Tickets" page lists the tickets of every plant

A new "Tickets" page lists the tickets of every reachable plant. A ticket describes a problem, is assigned to a colleague and discussed in comments, with people mentioned by @ and the components and events it concerns linked.

• The list filters and searches by plant, portfolio, status or assignee, and sorts by title, date or relevance.
• "My tickets" in the header shows how many tickets are assigned to the signed-in account.
• Each ticket keeps a timeline of every change: status, assignment, comments and linked components.
• A ticket can be closed when resolved, and reopened later if the problem comes back.
