[Applications] Applicant pipeline: employer accept/reject + status to applicant

InterestEvent gains a Status (ApplicationStatus: Interested→Accepted/Rejected; migration, default Interested). Employer/Listings shows each applicant's status with پذیرفتن/رد buttons (ownership-checked handlers update the status and notify the applicant via bell/SSE/push linking to the listing). The کارجو panel (/Me) now shows a status badge (در انتظار بررسی / پذیرفته شد / رد شد) on each applied shift/job. Reusable _ApplicantRow partial for the employer list.
