[DeckShare] Browse and open public decks with loading, error and accessibility states

Add a public-decks tab that lists decks published by other users using the server's deck visibility feature, previewing each deck's banner card, color identity, tags and upload time without downloading the deck list until the user opens it. - Add a public-decks tab with a shared-settings widget and a remote model that fetches the target user's decks and refreshes both automatically and on user request, with a loading indicator and a server-error message instead of a blank tab when the fetch fails or the connection drops - Render each deck as a focusable preview tile whose banner, color identity, tags and upload time follow the existing Preview settings, with the deck name announced as the tile's accessible name and Space/Enter opening the deck, mirroring the shared-deck preview tile - Show a message box when opening a public deck fails or arrives corrupted - Publish and unpublish decks from the server storage toolbar and context menu, toggling the deck's own visibility bit (what the server persists) rather than the inherited effective state, and batch the visibility refresh until the last in-flight change is acknowledged - Add the Show Upload Time setting so the tile's upload stamp can be hidden like the other preview details - Update the retranslateUi wiring for the new public-decks tab and rename the share action tooltip from "Deck share" to "Share link"
[DeckShare] Open shared decks via links with a gated preview flow
