build: Use spring-web instead of spring-webflux in spring-ai-retry

The dependency on spring-webflux was unnecessary, there was no code
inside spring-ai-retry that made use of it.

Also remove 'optional' from slf4j-api dependency (it's not optional,
if you don't have it on classpath, RetryUtils will fail to load).

Add explicit dependency on spring-webflux for modules that directly
import WebClient.

Fixes #3307
