feat: add Manage Nostr Keys page with export/import support

Master-detail key management view accessible from the Vault tab.
Left panel lists all profiles with truncated npubs; right panel
shows full npub/nsec (masked by default), copy buttons, JSON
export, and import from nsec string or JSON. Bumps version to
1.5.3 across package.json, both manifests, and Xcode project.
Production builds for Safari and Chrome included.
