Fix form field required states & missing fields per spec

- Admin add: add contact_public checkbox (matching edit form)
- All forms: formats checkbox-list now required
- All forms: jury promoteur·ice interne required, lecteur·ice interne/externe required
- All forms: licence select now required
- Admin edit: add E-mail de confirmation fieldset
- Partage: contact always visible when provided (no contact_public field)
- Partage: filter PACS from AP programs dropdown
- Server-side validation: formats, jury, licence required (create + edit controllers)
- Autofocus mappings for new validation errors
- No duplicate asterisks — verified across all rendered fields
- fix: add missing old() function in admin edit controller
- refactor: move admin email field to Backoffice as Contact interne, never send email
- Untrack admin.log (covered by .gitignore)
