feat(fedi): edit your own outbound replies (Update(Note))
services/ActivityPubService.js — deliverOutboxUpdate rewrites the stored reply (mention
re-added + #tags re-linked) and federates an Update(Note); listOutbox exposes the plain
editable text (outboxEditableText) to prefill the box; added to the default export.
routes/posts.js — POST /fediverse/:id/edit (owner only).
views/pages/authorize-interaction.ejs — an Edit details/textarea per reply in the manage list; + CSS.
