Build/dev emoji logging improved. Restored old plain lines, using intentionally different emoji than the main package.

App-supplied extra fields may carry raw ANSI color codes without a
reset, bleeding into the next line's IP column and following output.
Ensure access log lines begin and end with a reset, adding one only
where missing to avoid duplicate resets on well-formed lines.
