🐛 Image upload button hidden on web platform

[theflysurfer]

Bug

The image upload button (📎 icon) is intentionally hidden on the web platform via a Platform.OS !== 'web' condition in AgentInput.tsx.

Root Cause

// happy/sources/components/AgentInput.tsx ~line 1195
{props.onImagePickerPress && Platform.OS !== 'web' && (
    <Pressable ...>
        <Ionicons name="image-outline" ... />
    </Pressable>
)}

The Platform.OS !== 'web' guard completely removes the image picker button on web.

Impact

• Web: No image upload button visible → users cannot upload images at all
• Android: Button should be visible (condition passes), but user reports it's also broken — needs separate investigation

Expected Behavior

• Web should have an image upload button using <input type="file" accept="image/*">
• The existing useImagePicker hook uses expo-image-picker which may not support web — need a web-specific implementation (HTML file input + FileReader for base64)

Fix Plan

1. Remove the Platform.OS !== 'web' guard
2. Create a web-specific image picker (using native HTML <input type="file"> + drag-and-drop)
3. Add clipboard paste support (Ctrl+V) for web (as described in PRD)
4. Investigate Android separately if still broken
