CAMEL-23587: camel-jt400 - align Exchange header constant names with Camel
naming convention (#23470)
Renames the two Exchange header string values in Jt400Constants that were
not
in the Camel namespace (KEY, SENDER_INFORMATION) to CamelJt400<Name>,
following the convention used across the rest of the Camel component catalog
and matching the pattern established in CAMEL-23526 (camel-cxf), CAMEL-23522
(camel-mail), CAMEL-23461 (camel-aws-bedrock), CAMEL-23532
(camel-vertx-websocket / camel-atmosphere-websocket / camel-iggy), and
CAMEL-23576 (camel-jira).
- KEY: "KEY" -> "CamelJt400Key" (data-queue key for keyed-data-queue
read/write)
- SENDER_INFORMATION: "SENDER_INFORMATION" -> "CamelJt400SenderInformation"
The Java field names are unchanged so routes referencing the constants
symbolically continue to work; routes using the literal string values must
be
updated (documented in the 4.21 upgrade guide). The remaining constants
(MESSAGE, MESSAGE_ID, MESSAGE_FILE, MESSAGE_TYPE, MESSAGE_SEVERITY,
MESSAGE_DFT_RPY, MESSAGE_REPLYTO_KEY) were already Camel-prefixed and are
unchanged.
The generated Endpoint DSL header accessors on Jt400HeaderNameBuilder have
been renamed: kEY() -> jt400Key() and senderInformation() ->
jt400SenderInformation().
All existing tests use symbolic constant references and continue to pass.

+`Jt400Constants.KEY` is the data-queue key used for keyed-data-queue read and
