Fix Python syntax errors in agent files

Fixed 4 critical syntax errors found in recently merged agent files:

1. security_policy_generator.py:309 - Fixed mismatched bracket (} → ])
   for 'recommendations' list closing

2. mfa_manager.py:221 - Fixed mismatched bracket (} → ]) for
   'recommendations' list closing

3. press_release_writer.py:80,91,93 - Fixed f-string backslash errors
   by using double quotes for f-strings containing apostrophes

4. image_generator_prompt.py:192 - Fixed mismatched bracket (} → ])
   for 'stable_diffusion' list closing

All Python files now compile successfully.
