chore: point KAS defaults at platform.arkavo.net

[arkavo-com]

Summary

Stop using kas.arkavo.net and 100.arkavo.net as production KAS hosts.

Those names either time out or fail TLS (platform.arkavo.net is the only SAN on the live cert). Defaults, examples, and docs now use https://platform.arkavo.net.

[arkavo-com]

Docs-only mechanical kas.arkavo.net → platform.arkavo.net (README + MIGRATION_GUIDE). Source/tests already use localhost or https://platform.arkavo.net (PlatformConnectIntegrationTests). README still uses protocolEnum: .http (pre-existing; live tests use .https) — nit, not a leftover host.

test/build green. lint failed; this PR is markdown-only so that looks pre-existing (mergeable_state=unstable).
