⚡ Optimize CADC client capability status checks with concurrent execution

[tjzegmott]

💡 What: The optimization implemented
Replaced the sequential loop checking MINOC and Luskan capabilities in dtcli/utilities/cadcclient.py::status() with a concurrent.futures.ThreadPoolExecutor. A helper function processes the HTTP request and handles exceptions concurrently.

🎯 Why: The performance problem it solves
The original code looped over an array of 2 URLs, executing an independent HTTP GET request synchronously for each iteration. In scenarios with any sort of network latency, these blocking operations compound. Running the requests in parallel mitigates the cumulative latency overhead of independent network calls, reducing the function execution time.

📊 Measured Improvement:
Using an injected 1.0s sleep mock representing network latency in a benchmark script simulating status():

• Baseline (Sequential): 2.0005 seconds
• Optimized (Concurrent): 1.0020 seconds
• Speedup: Execution time for the function is halved (latency of network requests is bound to max(t_1, t_2) rather than t_1 + t_2).

Pull request overview

This PR optimizes CANFAR service status checks by running the Minoc and Luskan /capabilities requests concurrently instead of sequentially, reducing latency for independent network calls.

Changes:

• Adds ThreadPoolExecutor usage in cadcclient.status().
• Extracts per-URL status logic into a nested check_url() helper.
• Preserves the existing (minoc_status, luskan_status) return order.
