Backport of #8204 to `cloud/1.37`.
Cherry-picked merge commit `7b701ad07b1c34d121448e21d6f8b5c13ef07d73`.
## Original PR Summary
This PR improves keyboard event handling consistency and fixes an issue
where pressing Escape in nested input components would unintentionally
close parent modals/dialogs.
### Changes
- **EditableText keyup → keydown Migration**: Changed `@keyup.enter` to
`@keydown.enter` and `@keyup.escape` to `@keydown.escape` for more
consistent and responsive feedback
- Updated corresponding unit tests to use `keydown` triggers
> **Note**: The TagsInput escape key handling changes from the original
PR are not included in this backport because the TagsInput component
(#8066) was added after the cloud/1.37 branch was created.
