fix: Support right-click to paste file content into inputbar (#10730)

* feat: add right-click to paste text file content into input

Implemented context menu functionality for text file attachments that allows users to right-click on a text file attachment to paste its content directly into the input field.

Changes:
- Added onContextMenu prop to CustomTag component for handling right-click events
- Extended AttachmentPreview with onAttachmentContextMenu callback
- Implemented appendTxtContentToInput function to read and paste text file content
- Added clipboard support for copying file content
- Integrated context menu handler in Inputbar component

* use real path

* 🐛 fix: clear txt attachment after paste

* ✨ fix: improve attachment confirm flow

* update i18n

* 🎨 refactor: restyle confirm dialog

* format code

* refactor(ConfirmDialog): replace text buttons with icon buttons and remove i18n

- Replace text-based cancel/confirm buttons with icon buttons for better visual clarity
- Remove unused i18n translation hook as it's no longer needed
- Adjust styling to accommodate new button layout
