fix#14735
This PR fixes a remaining desktop case related to #14467.
The previous fix resolved incorrect translation in navigation panels,
but the detail page header tab title was still passing custom document
titles through `i18n.t()`, causing user-defined titles to be
unexpectedly translated.

## Summary by CodeRabbit
* **Refactor**
* Updated page title retrieval mechanism in workspace detail page
headers. The title is now sourced directly from the document display
metadata service instead of using the previous derivation method.

## The Fix
Fixes#14744.
Updated the menu input Enter key behavior so that pressing Enter now
saves the edited database column header name and closes the menu
immediately.
This reuses the existing `blur()` save flow, keeping the behavior
consistent with clicking outside the input.
The Tab key behavior remains unchanged and still saves through the
existing blur flow.
