Theseus 0.3.117: ICANN hosts that fail DNS show a DNS error, not a BCNR-register pitch

Browse source 
When a navigation hits ERR_NAME_NOT_RESOLVED and the TLD is a well-known
ICANN one (.com/.net/.io/country codes/…), Theseus now shows the DNS-
flavoured 'This name didn't resolve' page instead of the BCNR-flavoured
'That name isn't registered' page. The BCNR page framed the failure as
'nobody has claimed this on-chain name, want to register it on Sirius?'
— confusing when the user typed a real .com whose DNS is temporarily
broken (hostile Wi-Fi AAAA mangling is the usual cause). The DNS page
leads with retry and search instead, and still mentions BCNR was tried.

Non-ICANN TLDs (.bch, .x, …) keep the register-first framing. The
TLD set is a static whitelist of the common ones — covers the long
tail of real sites without being exhaustive. Add more as needed.
