Unify Specification Picker and Area for a consistent mobile experience

The new Specification Picker and Area Unification for mobile delivers a consistent, streamlined experience across iOS and Android, ensuring users interact with Specifications in the same way regardless of device or whether the "Spec by Area" feature is enabled. This update standardises the Specification listing and picker interface across Observations, RFIs and Inspections, reducing confusion, improving productivity and supporting seamless collaboration for all project stakeholders.
