…ing-boot-observation module Eliminates the verbatim duplication between dapr-spring-boot-autoconfigure (Spring Boot 3.x) and dapr-spring-boot-4-autoconfigure (Spring Boot 4.x): both modules previously held 100%-identical copies of ObservationDaprClient (~820 LOC) and ObservationDaprWorkflowClient (~400 LOC, including the W3C traceparent/tracestate formatters, repeated 4 times overall). Introduces a new Spring-agnostic module dapr-spring/dapr-spring-boot-observation under package io.dapr.spring.observation.client holding a single canonical copy of both decorators plus a package-private TraceContextFormat helper that replaces the 4 duplicated formatter copies. The module has zero Spring imports so it can be shared safely across Spring Boot 3.x and 4.x without API drift. Autoconfigure modules now depend on dapr-spring-boot-observation (optional), replacing their direct opentelemetry-api dependency. Consumers who skip observation wiring still don't pull OTel onto the classpath. OtelTracingClientInterceptor is now a private static final singleton on ObservationDaprWorkflowClient instead of allocated per client — justified by its existing javadoc which already stated it is stateless and shareable. Tests for the decorators themselves moved to the new module (33 pass); the Spring-wiring test DaprClientObservationAutoConfigurationTest stays in boot 3 with updated imports. Net: -1104 lines.

Description
Unfortunately, without adding trace propagation to the observations created in the SDK, traces are not correlated automatically.
With this PR, traces are correlated
WIthout this PR, we have a span, but that span is not correlated with downstream spans
Issue reference
We strive to have all PR being opened based on an issue, where the problem or feature have been discussed prior to implementation.
Please reference the issue this PR will close: #1725
