fix: mark redisConnectionFactory bean as @primary

When spring.threads.virtual.enabled is true, Spring Boot auto-registers
a redisConnectionFactoryVirtualThreads bean. This causes a
NoUniqueBeanDefinitionException since two ReactiveRedisConnectionFactory
beans exist without a primary designation. Adding @primary resolves the
ambiguity for ObjectProvider.getIfAvailable() calls.
