draft: Allow for custom ORD document extensions

Allow Custom ORD Document Extensions via Event-Based Registration

New Feature

✨ Introduces support for dynamically registering custom ORD document extensions at runtime via a CDS event mechanism (ord.extension.publish), in addition to the existing file-based custom ORD content approach.

Changes

• lib/extend-ord-with-custom.js: Exported getCustomORDContent and compareAndHandleCustomORDContentWithExistingContent individually from the module. Added a // TODO - To be deleted comment marking extendCustomORDContentIfExists for future removal.

• lib/ord.js: Updated the main ORD document builder to accept an optional extensions array as a second parameter. Replaced the single extendCustomORDContentIfExists call with an iteration over all provided extensions (plus the file-based custom ORD content), applying compareAndHandleCustomORDContentWithExistingContent for each.

• lib/services/ord-service.js: Added a constructor to OpenResourceDiscoveryService that initializes an extensions map and registers a listener for the ord.extension.publish CDS event. Incoming extensions are stored by ID, and when serving the ORD document, all registered extensions are passed to the ord() builder as an array.

The PR introduces a mechanism for programmatic ORD document extensions via a cds event system. A few substantive issues were found and flagged: the typeof "array" dead-code guard in the type check, the duplicate id argument passed to the logger, and most importantly the extension application order (file-based content always overrides caller-supplied extensions, which is likely backwards). Additionally, repeated init() calls will accumulate duplicate event listeners.
