fix: replace bare except clauses with except Exception (3 files)

[harshadkhetpal]

Summary

Replace bare except: clauses with except Exception: across 3 files (4 occurrences).

Per PEP 8, bare except: clauses should specify an exception type. Since none of these handlers re-raise the caught exception, except Exception: is the appropriate replacement — it catches all standard exceptions while still allowing KeyboardInterrupt and SystemExit to propagate normally.

Files changed:

• src/autoconf/main.py (1 occurrence)
• src/common/utils/jobs.py (2 occurrences)
• src/common/gen/save_config.py (1 occurrence)

Change pattern:

# Before
except:
    return False, f"exception :\n{format_exc()}"

# After
except Exception:
    return False, f"exception :\n{format_exc()}"

Testing

No behavior change for standard exceptions — KeyboardInterrupt and SystemExit will now propagate correctly instead of being silently caught.
