Offline Mode: Add a way to cancel uploads directly from Media Uploads screen

[kean]

Add a way to cancel uploads directly from the "Media Uploads" screen.

Note: this doesn't cover drafts sync yet, and I'm working on integrating this screen in more context, but wanted to keep the PRs small.

To test:

• Use the steps from the following issue to create a post with a dangling media upload
• Tap "Publish"
• ✅ Verify that the sheet shows a "Media failed to upload message" (it is a defect, but for the purposes of this PR, it's an expected behavior)
• Open "Media Uploads"
• Tap "More" and Tap "Cancel Upload" on the danling upload
• Tap "Back"
• ✅ Verify that the "Publish" button is now available and you can publish the post

Testing checklist:
