fix(logs): drop stray leading newline from SSE log event messages

Five broadcast('log', ...) calls in pipeline.js prefixed their message
with a literal \n (terminal-era vertical spacing). On the dashboard live
log each line is its own DOM entry, so the leading newline rendered as a
stray blank line at the start of the message. Removed the prefix from the
Phase 2 / Phase 3 / batch-paying / internet-down / internet-retest lines.

File-only logLine() audit-log separators are untouched (not event
messages — they write to disk for readability, not the SSE stream).
