Add a watchlist feature allowing users to bookmark creator keys and see them on a dedicated page

[Chucks1093]

Summary

Users have no way to save keys they are interested in without buying them. A watchlist feature that lets users bookmark creator keys and view them on a dedicated watchlist page would improve discovery and reduce navigation friction.

Scope

• Add a bookmark icon button to each creator key card on the marketplace and key detail page
• Toggle the bookmark state locally and persist it in localStorage keyed by wallet address
• Add a /watchlist route showing all bookmarked keys as a grid of key cards
• Show a 'Your watchlist is empty' empty state with a link to the marketplace when no keys are saved
• Show the total watchlist count as a badge on the navbar watchlist icon

Acceptance Criteria

• Bookmark toggles correctly on key cards and detail page
• Watchlist persisted in localStorage and restored on page reload
• Watchlist page renders correct bookmarked keys
• Empty state shown when watchlist is empty
• Navbar badge count matches the number of bookmarked keys

ETA: 12 hours

Hi, I'd like to claim this issue.

I will implement the watchlist feature across the client app:

• Add bookmark toggles on marketplace key cards and key detail pages, persisting saved keys in localStorage keyed by wallet address.
• Add the /watchlist page with a key card grid and an empty state linking to the marketplace.
• Add a navbar watchlist icon with a dynamic badge count reflecting saved keys.
• Ensure watchlist state restores seamlessly on page reloads and tests pass.
