♿️(frontend) improve version history modal accessibility

[Ovgodd]

Purpose

Fix accessibility issues in the version history list: each version button was announced as "version item" by screen readers, the focus was not visible when tabbing, and the HTML structure was invalid (<li> inside <button>). Also ensure the modal's accessible name is translated (e.g. "Historique des versions" in French instead of "version history modal" in English).

Proposal

• Replace static aria-label="version item" with a dynamic translated label including the version date
• Add visible focus background on version items for keyboard navigation
• Add aria-pressed and a live region to announce the selected version
• Change role="listbox" to role="list" so Tab/Enter works on all items
• Wrap each button in a <li> for valid <ul> > <li> > <button> structure
• Replace aria-label="version history modal" with aria-labelledby pointing to the translated h1
• Translate aria-label="version list" with i18n
