fix(DatabaseManager): make setLogger() reach every driver

[roxblnfk]

🔍 What was changed

• DatabaseManager::setLogger() now reaches every driver it knows about: drivers created before or after the call, drivers registered via addDriver(), and the drivers of databases registered via addDatabase().
• Behaviour change: a logger set explicitly via setLogger() now takes precedence over the LoggerFactory, for existing and future drivers. Before this, every driver created after the call got the factory's logger and the explicit one was ignored. This affected every Spiral application, because spiral/cycle-bridge always passes a LoggerFactory. The factory is still used while no logger is set.
• An explicitly set NullLogger is now passed to drivers as is. A NullLogger returned by the factory is still skipped, so drivers without a logger don't build the log context for every query.

Why?

The scenarios where the logger was lost are covered by DatabaseManagerLoggerTest, 21 cases. Before this fix, 7 of them failed on 2.x.

Review notes

• Database::withoutCache() clones its drivers, and the manager does not track those clones. A clone made before setLogger() keeps the logger it had when it was cloned. Tracking clones would need a shared logger holder between a driver and its clones, which is out of scope here. The limitation is documented on setLogger() and pinned by a test.
• testDatabaseManagerWithLoggerAndWithLoggerFactoryShouldReturnLoggerFromFactory asserted the old priority (the factory wins over an explicit logger). It is replaced by the opposite assertion, plus a test that the factory is still used when no logger is set.

Checklist

• Refs set logger to all drivers via DBAL->setLogger() orm#60
• How was this tested:
  • Unit tests added
  • phpunit --testsuite Unit and phpunit --group driver-sqlite pass locally
  • Psalm reports no new errors compared to 2.x
  • MySQL / Postgres / SQL Server suites were not run locally
