[CAMEL-22557] AS2: Fix configuration isolation and enable port sharing for inbound routes

[brunovg]

Description

This Pull Request addresses a major architectural limitation in the camel-as2 component where multiple inbound AS2 Consumers (routes) could not share the same port number.

The previous architecture led to two primary issues:

Port Binding Failure: The second route attempting to start would fail with an "Address already in use" error.

Configuration Collision: Even if the port binding was bypassed, encrypted messages failed with a NullPointerException or AS2DecryptionException because the shared server connection's cryptographic keys were overwritten or set to null and could not be retrieved by the correct Consumer.

CAMEL-22557: camel-as2 - Server-side DecryptingPrivateKey Conflict: Key from first route started is enforced for all subsequent routes on the same serverPortNumber

Thanks for the contribution!
Specifically the tests for the new parameter requestUriPattern are important and thise use case to have different decryptingPrivateKey for the servers listening on the same port.
I ran mvn -ntp verify -f components/camel-as2/ and there are many failures, try mvn install -Psourcecheck -DskipTests -f components/camel-as2/ also.
These changes should go first to main branch, then after merge to backport to the 4.10 and 4.14 branches.
I'm going to review the design changes.

Thanks, it looks like a great feature improvement! There's a few things that need to be adjusted, though (including tests, as reported).

The CI reports failures for the camel-catalog and endpointdsl, you can regenerate the as2 files with mvn install -DskipTests -pl :camel-endpointdsl,:camel-catalog
