Make all legacy security reports to use raw format

- This introduces and uses `:raw` format for all legacy reports,
  the ones that do not have yet proper parsers on Backend
- Raw format is needed to make Frontend be able to parse reports,
  without the need of decompressing,
- This also extends fixtures to seed security reports with database,
  even though parser code is part of EE
