fix(quake): prepare local service volume dirs

[giwaov]

Summary

• pre-create local monitoring data directories for Grafana and Prometheus during Quake setup
• pre-create local Blockscout logs/dets bind mount directories during Quake setup
• apply the existing local writable-directory permission handling to those service volume paths
• add a unit test covering the generated local service volume directories

Fixes #32

Testing

• cargo +1.93 fmt --check

I also tried cargo +1.93 check -p quake --bin quake, but this Windows environment is missing libclang for reth-mdbx-sys, so the build stops before checking the quake target.

Thanks, left two nits!

This comment needs a slight adjustment due to the changes made.

Suggested change

	/// can write to mounted volumes. Required on Linux where bind-mount permissions are strict.
	/// Create EL data dirs and set directory permissions so containers (running as non-root user)
	/// can write to mounted volumes. Required on Linux where bind-mount permissions are strict.

Extend the test to also verify that the directories have the correct permissions.

	let mode = fs::metadata(path).unwrap().permissions().mode() & 0o777;
	assert_eq!(mode, 0o777, "{} mode = {:o}, want 0o777", path.display(), mode);
	}
	}

Monitoring directories should not be created here. There's a setup method in MonitoringManager for that.

[giwaov]

Thanks, fixed.

I moved the monitoring data dir creation/permissions into MonitoringManager::setup() and kept set_local_testnet_directory_permissions() focused on the local testnet/blockscout/node volume dirs.

Also added a focused test for the monitoring setup path.
