fix(controller): make langfuse-tracer always-allow to avoid gateway restart

langfuse-tracer was conditionally added to plugins.allow based on
analyticsEnabled. On first boot or when the preference changed, this
mutated plugins.allow, which OpenClaw treats as a full gateway restart
(~11s drain + process restart on Windows).

Move langfuse-tracer to the unconditional always-allow list and use
the entries.enabled flag to toggle it. This way analytics preference
changes only flip the enabled flag (hot-reload path) instead of
mutating plugins.allow (full restart path).
