tickets panel: per-type filter chips (T-343)

A row of toggle chips below the filter box — one per pql ticket type,
ordered large→small (Initiative, Epic, Story, Task, Bug), each with its
TicketTypeColors dot + border. Single-click toggles a type; double-click
isolates it (chart-legend solo, fully reversible); disabling the last
enabled type snaps all back on so the list is never blank. ANDed with the
text filter; all on by default, nothing persisted.

One GestureDetector owns both onTap + onDoubleTap so Flutter disambiguates
single vs double. Wireframe updated + approved.
