feature(Twitter): Add "Extract URL" option to long-press menu for images

[tyuburarin]

What do you want?

Add a feature to extract (copy) image URLs from the long-press menu when long-pressing an image in the timeline, etc.

Specifically, when long-pressing an image, show the following options:

• Save image
• Extract image URL (copy)

Match the UI and behavior with the existing long-press menu for videos to keep consistency.

Why?

Currently, this app (piko) has a video URL extraction feature, but no image URL extraction feature exists.

• To get an image URL, users must go through an external site, which is inconvenient.
• Having this feature means users can get image URLs within the app without using external sites.
• Unifying the operation for videos and images reduces learning cost.
