feat(web): add Peer Card Seed Kits

Adds a /seed-kits page where users can author named "kits" of card
lines (e.g. "Personal core", "Work context") and one-click apply them
to any peer across any registered instance. Removes the chore of
manually re-typing the same identity facts into multiple agents.

Built-in starter kits are read-only but forkable. User kits live in
localStorage. The apply flow shows a side-by-side merge preview that
dedupes by the line's prefix (text before the first ":"), so applying
a kit with "Name: Ben Sheridan-Edwards" to a peer whose card already
has "Name: Ben" replaces the line rather than duplicating it.
