[PR] [backport camel-4.18.x] CAMEL-23630: add HeaderFilterStrategy to camel-dapr [camel]

oscerd opened a new pull request, #23889:
URL: https://github.com/apache/camel/pull/23889

   ## Backport of #23886
   
   Cherry-pick of #23886 (squash commit `72d13bd13fb`) onto `camel-4.18.x`.
   
   - **Original PR:** apache/camel#23886 โ€” CAMEL-23630: add HeaderFilterStrategy to camel-dapr
   - **Original author:** @oscerd
   - **Approved by:** @davsclaus
   - **Target branch:** `camel-4.18.x` (4.18.3-SNAPSHOT)
   
   ### What this backports
   
   Adds `DaprHeaderFilterStrategy` (exposed via `DaprComponent` / `DaprEndpoint` as the standard `headerFilterStrategy` option) and stops the `dapr-pubsub` consumer from copying the inbound CloudEvent's `pubsubName` / `topic` into the `CamelDaprPubSubName` / `CamelDaprTopic` headers. Those two constants are producer-direction routing headers that `DaprConfigurationOptionsProxy` reads back and prefers over the endpoint-configured destination, so a `from(dapr-pubsub).to(dapr-pubsub)` route incorrectly carried the inbound destination into the producer hop. The remaining CloudEvent metadata headers are unchanged.
   
   ### Backport notes
   
   - **Upgrade-guide entry omitted by design.** The original PR added a note to `camel-4x-upgrade-guide-4_21.adoc`, which does not exist on `camel-4.18.x`. Per project policy, upgrade-guide entries live on `main`; a matching `camel-4x-upgrade-guide-4_18.adoc` entry on `main` will follow so the 4.18.x line is documented.
   - **Clean cherry-pick:** all 12 code/generated files applied without conflict; only the `4_21` upgrade-guide hunk was dropped.
   - **Validated locally:** `mvn -pl components/camel-dapr clean install` on a `camel-4.18.x` worktree โ€” BUILD SUCCESS, 52 tests pass (incl. `DaprPubSubConsumerTest`), no regenerated-file drift.
