feat: seed dashboard, fix My tickets filter

- Add demo dashboard with 7 widgets to seed script
- Dashboard is_default=true — appears as home page on fresh seed
- Add views/dashboards/dashboardWidgets to seed reset
- Fix My tickets: now filters by first non-system user (not any owner)
- Pass owner param in sidebar My tickets link
- Update page.tsx view=my to respect owner URL param
- Scrip engine already sorts by sort_order (verified)
