Three coordinated changes on top of the section grouping:
1. **Mark as Critical** — a red chip on the New tab sets priority='3'
when submitted. The central post-create hook auto-applies a "Critical"
helpdesk.tag (shipped via fusion_helpdesk_central data XML, noupdate=1
so support can recolor without losing it on upgrade), giving support
a kanban-groupable signal that doesn't rely on remembering what
priority='3' means. Scoped to in-app-channel tickets only, so a
support agent manually setting Urgent on their own ticket isn't
silently tagged.
2. **KPI cards above the sections** — Total / Open / Closed / Critical
in a 4-up grid (auto-collapses to 2x2 under 540px). Each card uses
its own saturated gradient so it reads on both light and dark mode —
the dialog backdrop is irrelevant because the gradient brings its
own background. Counts are computed in JS from state.tickets so they
always match what's rendered below.
3. **Colored stage pills** — red Critical, green Solved, dark-yellow New,
orange Cancelled, blue for In Progress / Testing / On Hold. Critical
priority gets a *separate* red pill alongside the stage pill so you
keep stage info even on escalated tickets. Stage matching is
substring-based (lowercased) so a renamed "Resolved" or "Done" stage
on central still maps to the green pill.
Tests cover the new is_critical=True → priority='3' wiring and the
default omission so SLA / stage defaults keep working for normal
tickets. Bumps fusion_helpdesk to 19.0.1.7.0 and
fusion_helpdesk_central to 19.0.1.2.0. End-to-end smoke test verified
live: priority=3 + x_fc_client_label triggers the Critical tag.
