fix(wg1-setup.sh): escape WG_HOSTNAME in sed /etc/hosts cleanup
Escape regex metacharacters in WG_HOSTNAME before embedding into the sed
delete pattern so '.' (always present in hostnames like hyperstack1.wg1)
is treated as a literal dot rather than a wildcard.
Replace the literal-space anchor with [[:space:]] so tab-indented lines
in /etc/hosts are also matched and removed correctly.
