Fix lint: make scripts/demo/router.php PSR-12 compliant; tidy demo scripts

A semicolon inside a SQL comment (as in 001 and 003) cut statements in half and
made those migrations fail on a fresh database.

+
+## Why this exists
+
+Running a six-node Proxmox/Ceph cluster generates a steady stream of small problems: a drive with SMART warnings, a link that flaps, a certificate about to expire. Off-the-shelf helpdesks are heavyweight for that, and a plain todo list loses the history. Tinker Tickets is a small, opinionated ticketing system built for exactly this: tickets are created **automatically by monitoring** (and by hand), deduplicated so a repeating alert updates one ticket instead of flooding the queue, and every change is audited.

+
+**Kanban view** with per-column counts and priority-coloured cards:

+
+**Activity timeline**, derived from the audit log (creation, assignment, status changes, comments):
+
+![Activity timeline](docs/img/ticket-activity.png)
+
+**Command palette** (`Ctrl+K`) jumps to pages, saved filters and recently viewed tickets:
