feat(journal): trails profile-metadata field on federated actors

Browse source 
Mastodon renders PropertyValue attachments as the profile metadata
table — adds a '🥾 trails.cool' field linking to the user's canonical
profile, so it's human-visible that an account is a trails profile.
(The machine-readable signal stays NodeInfo; this is flair.) The link
carries rel=me so Mastodon can verify it once our HTML profile links
back.
