Revert "tech(question): discard_and_keep_track! ; are we really keeping track with default_scope { kept } ?"

This reverts commit d1155b7eeaaf1a9f80189e59667e109541fcb089.

feat(stats): support deleted_dossiers for last_four_months_hash and cumulative_hash. extract sanitize query & merge hashes in methdos

clean(rubocop): lint with rubocop

Update db/migrate/20211126080118_add_index_to_deleted_at_to_deleted_dossiers.rb

Co-authored-by: LeSim <mail@simon.lehericey.net>

fix(rubocop): avoid uneeded allocation

fix(migration): add concurrent index with expected synthax

fix(brakeman): add ignore message since group date_trunc evaluation is used by only ourself
