feat: post approval workflow, i18n completion, and multiple fixes

- Add approval process to posts (approver multi-select, rejected status column)
- Reorganize PostDetailPanel into Content, Scheduling, Approval sections
- Fix save button visibility: move to fixed footer via SlidePanel footer prop
- Change date picker from datetime-local to date-only
- Complete Arabic translations across all panels (Header, Issues, Artefacts)
- Fix artefact versioning to start empty (copyFromPrevious defaults to false)
- Separate media uploads by type (image, audio, video) in PostDetailPanel
- Fix team membership save when editing own profile as superadmin
- Server: add approver_ids column to Posts, enrich GET/POST/PATCH responses
