Pull request overview

This PR aims to eliminate duplicate HTML id attributes in the submission form, primarily by introducing a shared unique-id mechanism for dynamic form controls and adjusting template bindings to use property binding instead of string interpolation.

Changes:

• Added a static UniqueIdRegistry to generate de-duplicated element IDs for repeated dynamic form models.
• Updated dynamic form container + scrollable dropdown to use the registry-backed id getter and to release IDs on destroy.
• Updated the Clarin license selector option id binding to use Angular property binding ([id]) instead of interpolation.
