[UI] Mobile sticky action bar on shift/job details (native-app feel)

On mobile the action panel (CTA + map) stacked at the very bottom, so users had to scroll the whole page to act. Add a fixed bottom action bar (<=860px) with the primary «اعلام تمایل» button + a quick save, always reachable like a native app; when contact is revealed it becomes a «تماس با مرکز» tel: button. The in-aside primary CTA is hidden on mobile (.aside-apply) to avoid duplication, and pages get bottom padding (.has-action-bar) so the bar never covers content. Desktop layout unchanged (bar hidden, sidebar CTA shown).
