hand agents the dashboard port, pinned claude and otel labels at container start

Browse source 
The three values that differ per host (deploy.hive-controller.dashboardPort,
claudeCodePackage and otel.extraResourceAttributes) no longer go into the
meta flake. hive-priv writes them into the container's
/etc/hyperhive-hive-facts with the hive name and domain, and the agent
reads them at boot:

- HIVE_DASHBOARD_PORT reaches every unit through the hive-facts generator;
  the web UI still defaults to 7000 without it.
- `claude` on PATH is a wrapper that runs HYPERHIVE_CLAUDE_CODE_PATH's
  claude when it is there, and the container's own claude-code otherwise.
  The host's serve.json keeps gc-rooting the pinned build.
- OTEL_RESOURCE_ATTRIBUTES moves out of the units' Environment= into a
  boot-time generator, which appends HYPERHIVE_OTEL_EXTRA_RESOURCE_ATTRIBUTES.

The agent options services.hyperhive.agent.claudeCodePath (now a removed
option) and otel.extraResourceAttributes go; only the meta render set them.
render_flake takes no HiveEnv any more, so the memory-cap render test and
render_hive_flake_at, which only existed to vary HiveEnv into the render,
go with it.
