feat: Add option to choose image/video quality like WhatsApp

[diegolmello]

We would have to implement quality and videoQuality from expo-image-picker https://docs.expo.dev/versions/latest/sdk/imagepicker/#imagepickeroptions

To be done

• Add a button on ShareView header to toggle between SD/HD. It can be just a text for now.
• We’ll have to play with the values, but a compression of 0.5 might be enough
• Default SD
• The option needs to be considered on all files sent on the same upload, but fallback to SD afterwards for future uploads

I explored the image quality and video quality options from expo-image-picker, but these only apply when the user selects the image or records the video. Since the SD/HD toggle is meant to work at upload time, it won’t affect already-selected media.
To implement this behaviour more reliably, I suggest using expo-image-manipulator after the media is picked. This way, we can apply compression based on the toggle before upload, offering more control and ensuring the SD/HD choice affects all selected files correctly.
Let me know if you're okay with this approach. @diegolmello

@JASIM0021 I think that's a good idea.
