- added backup codes for 2 factor authentication

- npm updates
- coverage validation: elevation ust be positive, depth must be negative
- vinejs-provider.js: get enabled extensions from database, not via validOptions.extnames
- vue components for backup codes: e.g.: PersonalSettings.vue
- validate spaital coverage in leaflet map: draw.component.vue, map.component.vue
- add backup code authentication into Login.vue
- preset to use no preferred reviewer: Release.vue
- 2 new vinejs validation rules: file_scan.ts and file-length.ts
