links: clickable [[wiki-links]] on cards

LinkedText now makes each [[link]] segment interactive: click (or Enter when
focused) resolves the title and opens the target note, creating it first if
it doesn't exist. Reuses the palette's /?open=<id> open path. @click.stop /
keydown.stop keep the surrounding card's click-to-open from also firing.
