Stacked on #392.

A website env, and a multi env's websites, now get the same harness treatment as MCP servers:

• sync_env_clock syncs a website env's site and a multi env's websites; a site that doesn't follow the clock is tolerated. With main's timezone (feat(sync_env_clock): an optional timezone reads virtual_time in the zone and tells every synced server (FD-5003) #442), every synced server, website or MCP server, is told the zone, and a site that follows the clock but can't take the zone fails the step, as an MCP server does.
• snapshot_env exports each website child through its data plane; one without a data plane is skipped with a warning, and the step fails only if nothing is exported.
• A config broadcast (apply_server_config with "*") reaches websites, and skips one without a card or the extension, even in strict mode, so a multi env with an older site behaves as before.

legacy_protocol.backing_servers(env) lists MCP servers then websites; on a name clash the MCP server wins.

Test

Unit suite and protocol tests: 12,607 passed, lint clean.
tst/unit/task_step, tst/unit/env, tst/unit/providers: 5303 passed (one timing test in child_sessions_test.py, untouched here, flaked once and passes on rerun).

The PR appears safe to merge; the previous snapshot finding is fixed and no new actionable issues were found.

Summary

Gives websites the same clock, snapshot, and config steps as MCP servers.

• Website servers can follow the task’s virtual clock.
• Snapshots can include state from website servers.
• Config broadcasts can reach website servers.
