docs(deliverability): correct SNDS entry URL (snds.microsoft.com does not resolve)

Browse source 
Use the legacy sendersupport.olc.protection.outlook.com/snds/ (308-redirects) or
the direct substrate.office.com/ip-domain-management-snds/SNDS app URL. Flag that
snds.microsoft.com has no DNS.

register IPs **207.174.124.94** and **207.174.124.107** (the two live stream IPs;
add .90 and .71 if you want full coverage). Verification goes to a role address
on the IP's domain (use `postmaster@` or `abuse@performancewest.net`, now live).

the same IPs + complaint-destination mailbox **`fbl@performancewest.net`**.
