fix(comments): stop linking deleted comments to their author's profile master
Deleted-comment tombstones arrive from the backend with an empty handle but the author's real DID (the backend expects the frontend to render "[deleted]"). The comment meta row rendered UserLink unconditionally, producing a bare "@" that hyperlinked to /profile/<did> — quietly de-anonymizing who wrote the deleted comment. Changes: - Comment: when isDeleted, render a muted non-linked "[deleted]" label in place of UserLink (no avatar, no profile link) - Comment: suppress the OP microphone badge for deleted comments, which would leak authorship the same way via the DID comparison - i18n: add comment.deletedAuthor ("[deleted]") to en.json Verified in Firefox against the dev stack: backend tombstones render "[deleted] <time> ago" with no profile links, the in-place delete flow updates reactively without a reload, and non-deleted comments still show their author and OP badge.
