fix(backend): Fix Black formatter syntax and indentation errors

Fixed 2 critical errors that broke Black formatter:

1. routes/ssh_settings.py:163
   - Fixed indentation error from incorrectly placed FIXME comment
   - Changed from: "# FIXME:             await" (mid-line comment)
   - Changed to: "            # await" (properly indented)

2. services/rule_specific_scanner.py:233
   - Fixed syntax error from misaligned if statement
   - Corrected indentation of "if False:" to match function scope
   - Added clarifying comment about disabled code

3. Minor Black formatting fixes:
   - Added blank line after imports in rule_scanning.py
   - Added blank line after imports in plugin_marketplace_service.py
   - Fixed comment formatting in system_settings_unified.py
   - Added blank line before get_framework_statistics_from_files

These were syntax errors introduced by automated sed fixes in previous
commit (235ee20). Black formatter can now parse all Python files.
