Add photos folder option in iPhone mobile app

Objective

• On iPhone, give users a clear way to pick files from Photos (or the system photo library) when attaching to a workorder, matching what Android users already see in practice.
• Keep one coherent upload path to the inspection attachments API so behavior stays predictable across platforms.

Background

• Product feedback: the iOS build of the Attik mobile app does not surface a Photos / library-style option when adding attachments, while Android does for the same flow.
• The inspection screen mounts Workorder files via AttachmentsSection, which today calls DocumentPicker.getDocumentAsync from expo-document-picker with type: "*/*" and no Platform.OS branching—iOS and Android rely on each platform’s document picker UI, which differs (Android often exposes gallery/Photos more prominently).
• The app does not currently list expo-image-picker (or another photo-library module) in package.json; uploads go through uploadInspectionAttachment in inspectionAttachmentsService.ts as multipart FormData.

Scope

Mobile — attik-mobile repo

• Primary UI: components/inspection/AttachmentsSection.tsx (handleAddFile → DocumentPicker.getDocumentAsync). Parent usage: app/(app)/inspection/[id].tsx (renders AttachmentsSection for the inspection).
• Service layer: lib/services/inspectionAttachmentsService.ts (POST inspection/{id}/attachments)—reuse the same upload contract; scope is client pick UX and file URIs, not backend route changes unless discovery shows an iOS-specific upload gap.
• Decision needed: how iOS users choose Photos—extend the document picker configuration, add a secondary action (e.g. “Choose from Photos”) alongside files, or a single chooser that combines sources—plus any Info.plist / Expo config entries required for photo library access.
• Decision needed: whether Android behavior must remain unchanged or can be lightly unified for parity.
