CAMEL-23812: camel-milo better username & password handling

[davsclaus]

Summary

• Adds explicit username and password options to MiloClientConfiguration so credentials no longer need to be embedded in the endpoint URI
• Fixes issues with special characters in passwords (e.g. @, $, ?, %) that broke URI parsing and replaceFirst() regex matching
• Rebuilds discovery URI from parsed URI parts instead of string manipulation
• Includes regenerated metadata files (configurers, URI factories, JSON) that were missing from the original PR

Based on the work from @robMate in #24185, with regenerated metadata and formatting fixes added on top.

Test plan

• ExplicitCredentialsTest added to verify explicit username/password handling
• Build camel-milo module: cd components/camel-milo && mvn verify
