Subject: [PATCH] fix: support IPv6 addresses in ping monitor

## Changes
- Fixed ping host sanitization regex that stripped everything after
  the first colon, which destroyed IPv6 addresses like 2001:db8::1
- New regex properly handles bracketed IPv6 ([::1]:port), bare IPv6,
  and IPv4/hostname:port formats separately

## Closes
Fixes #3053
