feat: Add address publish actions across clients

[macterra]

Summary

• add per-address Publish/Unpublish actions to the identity Addresses tab in the gatekeeper client, keymaster client, react wallet, and browser extension
• store the published address in the agent's address property and ensure only one address is published at a time
• keep published-address UI state in sync on startup, refresh, and address removal, and document that the two KeymasterUI.jsx copies must stay identical

Testing

• npm run build --prefix apps/gatekeeper-client
• npm run build --prefix apps/keymaster-client
• npm run build --prefix apps/react-wallet
• npm run build --prefix apps/browser-extension

Pull request overview

This PR adds per-address Publish/Unpublish controls across the various clients’ identity address UIs, persisting the “published” address into the identity’s didDocumentData.address field (via mergeData) and keeping the UI state synchronized across refresh/startup/removal flows.

Changes:

• Add Publish/Unpublish actions to address lists (React wallet, browser extension, Gatekeeper client, Keymaster client) and visually highlight the published address.
• Sync published-address state by reading didDocumentData.address on refresh/resolve, and clear it when the published address is removed.
• Document that apps/gatekeeper-client/src/KeymasterUI.jsx and apps/keymaster-client/src/KeymasterUI.jsx must remain identical.
