Add ability to cancel link previews

[andremion]

🎯 Goal

Introduce the ability to cancel link previews in the message composer.

🛠 Implementation details

• Added a cancelLinkPreview method to MessageComposerController and MessageComposerViewModel.
• Updated ComposerLinkPreview to accept an onCancel callback.
• When sending a message, if linkPreviews is empty, skipEnrichUrl will be set to true.
• Connected the cancel action in the UI to the new methods.
• 🚨 Breaking change: Updated ChatComponentFactory and MessageComposer to pass the new onCancelLinkPreviewClick callback.
