Goal: Any authenticated non-banned user can file a report against a post, comment, or user, with all validation rules enforced and the report visible in the moderation queue.
→ "A user can report content for any valid reason, duplicate and self-reports are rejected with clear error messages, and every filed report appears in the admin queue with its full audit trail."

Features in this milestone:

• #26 — Report filing UI (reason selector, details field, submit)
• #27 — Validation feedback (self-report, duplicate, banned reporter — all surface as inline errors)
• #28 — Report status display (PENDING / AI_SCREENING / ESCALATED_TO_HUMAN / RESOLVED_AUTO / RESOLVED_HUMAN / DISMISSED)
• #29 — Report queue list view (filterable by status, reason, content type)
• #30 — Report detail view (target content, reporter info, reason, details, audit trail)
• #31 — Status pipeline stepper component (shows current stage visually)
• #32 — useReports hook + reportService.ts
• #33 — ReportReason and ReportStatus enums aligned with backend

Definition of Done:

• All features merged to main
• All three validation rules enforced: no self-report, no duplicate, no banned reporter
• Report audit log renders all entries with timestamps
• Queue updates without full page reload after a new report is filed
• No TypeScript errors
• Tested on mobile viewport
• Backend team sign-off on Report API contract and validation error response shapes
