Fredrik Adelöw b33f8450b5 fix(catalog-backend): fix irreversible database migration down functions

Five migration down functions were broken, causing the SQL report to flag
them as not reversible. All issues were pre-existing bugs that were never
caught because the down migrations had never been exercised under the
reversibility checker.

- 20241003170511: add .notNullable() to both up and down when altering
  locations.target, preventing the NOT NULL constraint from being silently
  dropped by knex's .alter() when widening varchar(255) to text.
- 20220116144621: implement a real down function that recreates the three
  dropped legacy tables (entities, entities_search, entities_relations)
  with correct columns and indices.
- 20210302150147: drop dependent tables in the correct order to avoid a
  FK constraint violation, and fix a typo (references → refresh_state_references).
- 20201005122705: drop full_name from entities (not entities_search), and
  restore entities_unique_name with the correct column order (kind, name, namespace).
- 20200702153613: use table.integer('generation') instead of table.string()
  in the down function to restore the correct column type.

patch

Fixed several database migration down functions that were not properly reversible, causing the SQL report to show warnings:

20241003170511_alter_target_in_locations.js: both up and down now include .notNullable() when altering the locations.target column, preventing the NOT NULL constraint from being accidentally dropped when widening the column type from varchar(255) to text.
20220116144621_remove_legacy.js: the down function now properly recreates the three dropped legacy tables (entities, entities_search, entities_relations) with correct columns and indices.
20210302150147_refresh_state.js: the down function now drops dependent tables in the correct order (avoiding a FK constraint violation) and fixes a typo where the table was referred to as references instead of refresh_state_references.
20201005122705_add_entity_full_name.js: the down function now drops the full_name column from entities (not entities_search), and restores the entities_unique_name index with the correct column order (kind, name, namespace).
20200702153613_entities.js: the down function now uses table.integer('generation') instead of table.string('generation'), restoring the correct column type.
