profile: drop unused title/signature/defaultAgentId fields

These were aspirational placeholders — stored to localStorage but never
read by anything. Removed from the form, types, and persistence layer.
Local profile is now just the avatar URL mirror, which the appbar reads
before the server profile fetch resolves on mount.

Preferences card renamed to "Avatar" since that's all that's left.
Re-add server-backed if/when something actually consumes them.
