♿️(frontend) replace ARIA grid pattern with list in docs grid

[Ovgodd]

Purpose

The document grid used role="grid" with role="row", role="gridcell", role="rowgroup", and role="columnheader". This ARIA grid pattern requires full keyboard navigation with arrow keys which it's not implemented and demand to much complexity, . With role="grid", some screen readers switch to a mode where arrow keys are handled by the page; since the page did not implement grid navigation, that interaction did not work as expected.

Proposal

• Replace role="grid" / role="row" / role="gridcell" / role="columnheader" / role="rowgroup" with role="list" / role="listitem", matching the actual semantics (a list of documents, not a data grid)
• Mark visual column headers (Name, Updated at) as aria-hidden="true" since they are no longer part of the list semantics
• Add translatable screenReaderInstructions and announcements on DndContext (accessibility prop) so SR copy can be localized via i18n
