Fix 27 TS errors in resources.spec.ts - Add missing Feature properties

Added missing optional properties to CSAPI Feature type definitions:

**ProcedureFeatureProperties:**
- inputs, outputs, parameters, method (SensorML I/O definitions)
- components, connections (SensorML structure)

**PropertyFeatureProperties:**
- baseProperty (for derived properties)
- statistic (e.g., 'mean', 'sum', 'max')

**DatastreamSchema:**
- type (SWE component type)
- elementType, fields (SWE structure)
- elementCount (for DataArray)

**DatastreamFeatureProperties:**
- encoding (observation encoding)

**DeploymentFeatureProperties:**
- id, uniqueId (identifiers from SensorML)
- keywords, identifiers, classifiers (discovery metadata)
- contacts, documents (references)
- securityConstraints, legalConstraints (constraints)

These properties are populated at runtime from SensorML/SWE parsing.
Remaining 27 errors in resources.spec.ts involve accessing nested unknown
structures and Geometry coordinates - tracked separately.
