fix: Ensure Message Send Requires Key 🔑 (#1281)

* fix: only allow message send when key is provided when required
- create useRequiresKey hook
- pass same disabled prop to Textarea, AttachFile, and SendButton
- EndpointItem: add localization, stopPropagation, and remove commented code
- separate some hooks to new Input dir
- completely remove textareaHeight recoil state as is not needed
- update imports for moved hooks
- pass disabled prop to useTextarea

* feat: add localization to textarea placeholders
