Improve mobile/tablet responsive, fix structured data, update deploy schedule and fix HTML issues

- Add responsive breakpoints (sm/md) to event_detail.html.twig: adaptive titles, stacked ticket layout on mobile, reduced padding/spacing
- Add responsive breakpoints to order templates (guest, summary, public, payment, success): adaptive typography, padding, and layouts
- Fix BreadcrumbList JSON-LD: escape names with json_encode, remove item URL from last breadcrumb
- Update deploy.yml cron schedule from 3h/13h/19h/23h to 1h/22h
- Add <title> tags to rgpd_deletion.html.twig and rgpd_access.html.twig
- Add scope attributes to all <th> tags in rgpd_access.html.twig
- Replace deprecated width/cellpadding/cellspacing HTML attributes with CSS in scan_force_notification email
