Several fixes

Schema Changes (rdls_schema_v0.3.json)
Removed geometry field from Location definition and updated spatial description
Fixed risk_data_type structure - moved $ref under items array to match proper schema pattern
Changed oneOf to anyOf for date validation in Period start/end fields

Metadata Editor Changes (RDL_MDE.html)
Fixed bbox/centroid empty values - now outputs empty/undefined instead of [0,0] when not specified
Disabled countries field when spatial_scale is 'global' - auto-disables with visual indication and info note
Fixed numeric field types - added convertValueBySchema() function to convert string inputs to numbers/integers based on schema (fixes spatial_resolution, event_count, occurrence, event_rate, return_period, value, span, etc.)
Removed geometry references from MDE code
Added cleanEmptyValues() function - recursively removes empty arrays, empty strings, and null values from exported JSON/XML and GitHub publishes
