-- A normal User with the historical membership-level access_all bit reached every collection of the
-- organization with full read/write, but held no collection-management authority. Mapping that onto
-- the Custom role would add authority, clearing the bit would remove existing access — so instead,
-- materialize the reach as explicit per-collection assignments while the source bit still exists.
-- `manage` stays FALSE, so no management authority is invented. This is the same approach Bitwarden
-- took when it retired `accessAll`; the one behavioral difference is that the access is no longer
-- dynamic, i.e. collections created later are not added automatically.
--
-- Step 1: a pre-existing assignment was overridden by access_all (full read/write regardless of
-- read_only/hide_passwords), so relax it to match what the member actually had.
