[WIP] **_{_{}} Optional requests handling still crashes when module is absent**

[Copilot]

• Analyze current is_pi_reachable implementation for potential issues with requests module
• Make exception handling more explicit to avoid potential AttributeError
• Test the fix to ensure it works both with and without requests module
• Verify no regressions in existing functionality

<issue_description> Optional requests handling still crashes when module is absent

is_pi_reachable repeats the same except (requests.exceptions.RequestException, urllib_request.URLError) pattern as the other client. When requests is not installed the module fails to import with AttributeError before any fallback to urllib can happen, so the client with improved pause logic still cannot run on machines without that optional dependency.
