restore(mobile): restore mobile/ directory to pre-d2217531 state

Restored mobile/ from d22175310a711e7ebdd8062ae29a54f0136dc3f6^ (parent commit d94e9ca4bc). Commit d22175310a (google-labs-jules[bot], 2026-03-23T14:45:22Z) introduced an SSRF security fix for IMAP connections but unintentionally deleted or truncated a large number of files across the repository, including 24 files under mobile/. This commit targets only the mobile/ directory and restores the following files to their pre-d2217531 state: - mobile/README.md - mobile/app.json - mobile/app/(tabs)/_layout.tsx - mobile/app/(tabs)/file-detail.tsx (re-added) - mobile/app/+not-found.tsx (re-added) - mobile/app/_layout.tsx - mobile/eslint.config.js (re-added) - mobile/package-lock.json - mobile/package.json - mobile/src/context/ShareContext.tsx - mobile/src/i18n/de.json (re-added) - mobile/src/i18n/en.json (re-added) - mobile/src/i18n/es.json (re-added) - mobile/src/i18n/fr.json (re-added) - mobile/src/i18n/index.ts (re-added) - mobile/src/i18n/it.json (re-added) - mobile/src/screens/FileDetailScreen.tsx (re-added) - mobile/src/screens/FilesScreen.tsx - mobile/src/screens/LoginScreen.tsx - mobile/src/screens/ProfileScreen.tsx - mobile/src/screens/UploadScreen.tsx - mobile/src/screens/WelcomeScreen.tsx - mobile/src/services/api.ts - mobile/src/utils/mimeTypes.ts (re-added) - mobile/src/utils/normalizeUri.ts (re-added) Security fixes introduced by d2217531 that are unrelated to mobile/ (IMAP SSRF fix in app/utils/network.py and app/tasks/imap_tasks.py) are preserved — this restore targets only files under mobile/.
