CTCP ACTION messages (/me) were relayed with raw \x01 bytes, rendering
as boxed-X characters in OwnCast. Detect the ACTION pattern, extract the
body, and format it like traditional IRC clients. Also strip \x01 in
irc_format as a safety net for other CTCP leakage.

Add irc_format module that removes mIRC control codes (bold, color,
italic, underline, reverse, strikethrough, monospace, reset) before
forwarding to Owncast. Color codes with fg/bg digit params are
consumed correctly. Multi-byte UTF-8 (emoji, accented chars, CJK)
is preserved.
