Refactor the image handling workflow to decouple image selection from the upload process. This improves user experience by allowing users to continue composing posts or trades while images are queued for upload, and increases reliability by using a centralized pending image utility.
- **Deferred Uploads**: Replaced immediate image uploads in `CreatePostScreen`, `PostDetailScreen`, and `CreateTradeScreen` with a "pending" state. Images are now uploaded in bulk during the final submission phase.
- **BlockEditor Enhancements**:
- Updated `useBlockEditor` to support asynchronous batch uploading of all pending images via a new `uploadPendingImages` method.
- Removed inline uploading overlays in favor of a more robust state-driven approach.
- Improved `BlockEditorHandle` to expose block retrieval and batch upload capabilities.
- **API Layer Improvements**:
- Migrated native image uploads from standard `FormData` to `expo-file-system`'s multipart upload to resolve compatibility issues with recent React Native versions.
- Maintained `fetch` + `Blob` logic for web platform compatibility.
- **New Utilities**: Introduced `src/utils/pendingImages.ts` to manage the lifecycle of local (pending) vs. remote (uploaded) images across the application.
- Implement `segmentsToBlocks` utility to convert message segments into editable blocks.
- Update `BlockEditor` and `useBlockEditor` to support initial block loading and improved image upload handling.
- Add logic to `CreatePostScreen` to automatically switch to long-post mode when image segments are detected and preserve data when toggling modes.
- Update `AboutScreen` to make the ICP filing number clickable.
- Refactor mapper imports to use the updated data model paths.
Introduce a new `BlockEditor` component and upgrade the post/message
rendering system to support rich text segments (images, @mentions,
votes, and post references).
- Implement `BlockEditor` for long-form post creation with image
embedding support.
- Upgrade `PostContentRenderer` and `SegmentRenderer` to handle
complex segment types including inline images and block elements.
- Refactor `PostCard` to use segment-based content and image
signatures for optimized memoization.
- Centralize segment partitioning logic in `segmentUtils.ts` to ensure
consistent rendering across chat and post modules.
- Update `PostRepository` and `Post` entity to support the new
`segments` data structure.
