LWLP-1215: bugfix: DAO test fixtures breaking

[etsien]

Summary

Soft-delete committed lightwell RepositoryConfiguration rows (org_id -3, -4) at the start of each DAO test transaction in DaoSuite.SetupTest(). This prevents committed lightwell repos from leaking into test assertions that assume a clean database. The Rollback() in TearDownTest() restores the rows, so no data is permanently affected.

The fix is a 3-line addition in pkg/dao/suite_test.go. No test assertions, seed data, or production code change.

Testing Steps (reproduction)

1. Start the local database:

   make db-up db-migrate-up

2. Seed lightwell repos to simulate a developer who has run the importer:

   podman exec cs_postgres-content_1 psql -U content -d content -c "
   INSERT INTO repositories (uuid, created_at, updated_at, url, origin, content_type, public)
   VALUES
     ('aaaaaaaa-0000-0000-0000-000000000001', now(), now(), 'https://repo.maven.apache.org/maven2/', 'lightwell', 'maven', false),
     ('aaaaaaaa-0000-0000-0000-000000000002', now(), now(), 'https://pypi.org/', 'lightwell', 'python', false)
   ON CONFLICT DO NOTHING;
   
   INSERT INTO repository_configurations (uuid, created_at, updated_at, name, label, arch, versions, org_id, repository_uuid)
   VALUES
     ('bbbbbbbb-0000-0000-0000-000000000001', now(), now(), 'maven-test', 'maven-test', 'any', '{any}', '-3', 'aaaaaaaa-0000-0000-0000-000000000001'),
     ('bbbbbbbb-0000-0000-0000-000000000002', now(), now(), 'python-test', 'python-test', 'any', '{any}', '-3', 'aaaaaaaa-0000-0000-0000-000000000002')
   ON CONFLICT DO NOTHING;
   "

   These rows have NULL feature_name, which passes the feature gate unconditionally.

3. Without the fix (on main), confirm the tests fail:

   CONFIG_PATH="$(pwd)/configs/" go test ./pkg/dao/... -count=1 -timeout=180s \
     -run "TestRepositoryConfigSuite/(TestListNoRepositories|TestListPageLimit|TestListFilterOrigin|TestListFilterExtendedRelease|TestListFilterStatus)" -v

4. With the fix, confirm all tests pass:

   CONFIG_PATH="$(pwd)/configs/" go test ./pkg/dao/... -count=1 -timeout=180s \
     -run "TestRepositoryConfigSuite" -v

5. Confirm TestAdminTaskSuite/TestSort still passes:

   CONFIG_PATH="$(pwd)/configs/" go test ./pkg/dao/... -count=1 -timeout=60s \
     -run "TestAdminTaskSuite/TestSort" -v
