changes how transport is selected to use a parameter saved in hgrc, instead of determining based on the host name. This will let #406 define a 3rd option so we can release experiments without having a fallback.

AI summary

Summary

• New HgTransportKind enum (HgWeb / Resumable) replaces the implicit "does the URL contain 'resumable'?" heuristic for picking between hgweb and HgResume transports.
• Transport is now stored in .hg/hgrc under a new [chorus] section (transport = hgweb / transport = resumable), independent of the repository URL.
• ServerSettingsModel: BandwidthItem now wraps HgTransportKind; Transport property exposes the choice for both Lexbox and custom URLs. SaveSettings writes the transport to hgrc in addition to setting the address.
• Lexbox host simplified: the resumable variant used to require a separate resumable.* hostname; that coupling is removed. Both transports are served from hg-public/hg-private. Legacy resumable.languageforge.org URLs are rewritten to the canonical host on load.
• Bandwidth dropdown now appears for custom URLs as well as Lexbox (previously it was hidden for custom URLs).
• InternetCloneSettingsModel.SetRepositoryAddress passes the selected transport to both the address and the hgrc [chorus] section.
• Integration test helper no longer puts "resumable" in the repo code; the transport is explicit via HgTransportKind.Resumable.
• New unit tests cover: transport round-trips on save/reload, saved transport overriding URL guess, custom URL transport, AliasName not including bandwidth, and HttpRepositoryPath transport override.

Testing

• 96/96 LibChorusTests pass on net8.0 and net462 (ServerSettingsModel, InternetCloneSettingsModel, RepositoryAddress, HgRepository test classes).
• 22/22 Chorus.Tests server-settings and clone tests pass on net462.
• Docker-based integration tests (HgResumeSendReceiveTests) not run locally.
