feat(tls): cipher suite presets and a uTLS fingerprint warning

Adds PattN's semi-python and real-firefox client cipher lists as presets
in the cipher suites picker. A preset replaces the whole list because the
order is part of the ClientHello.

The inbound TLS form now warns when cipher suites are set under a uTLS
fingerprint other than "unsafe": clients ignore them there, while an
empty fingerprint is already pinned to unsafe in share links.
