fix(tests): extend Respawn + collection config for UDT-010 temporal tables

Follow-up of B1 (V010 migration). Issues found when running the full suite
cross-assembly:

1. Respawn 'Cannot delete rows from a temporal history table' error:
   4 per-class Respawner configs in SIGCM2.Application.Tests did not
   include the newly-created *_History tables introduced by V010
   (Usuario_History / Rol_History / Permiso_History / RolPermiso_History).
   The engine rejects direct DELETE on system-versioned history tables.
   Extended TablesToIgnore in all 4 configs.

2. FK_RefreshToken_Usuario violation in RolRepositoryTests.InitializeAsync:
   Manual 'DELETE FROM Usuario' failed when residual RefreshTokens from
   prior suites existed. Added 'DELETE FROM RefreshToken' before the
   Usuario cleanup to respect FK order. Latent bug surfaced by a new
   test-run ordering — not UDT-010 specific, but fixed in scope.

3. UQ_Usuario_Username duplicate admin race:
   TransactionScopeSpikeTests (B0) and V010MigrationTests (B1) were
   missing [Collection("ApiIntegration")], causing them to run in
   parallel with the rest of SIGCM2.Api.Tests and race on SeedAdmin.
   Serialized by adding the Collection attribute.

Suite now passes cross-assembly: 130/130 Api.Tests + 336/336 Application.Tests.
