style(logs): wrap long log lines to the next line (admin + live)

Long log lines were truncated with an ellipsis on /live (.log-entry had
white-space:nowrap; overflow:hidden; text-overflow:ellipsis), hiding the
tail of long messages; on admin, long unbroken tokens could overflow.

Wrap instead of hide:
- live.html: .log-entry wraps (white-space:normal; flex-wrap:wrap;
  align-items:flex-start; overflow-wrap:anywhere) and .log-msg flows to
  the next line (flex:1 1 auto; min-width:0; overflow-wrap:anywhere;
  word-break:break-word) — the meta pills stay on the first line, the
  message wraps in its column.
- admin.html: .log-entry gains overflow-wrap:anywhere + word-break so
  long addresses / base64 memos / URLs break instead of overflowing.

CSS only; no behavior change.
