fix: update type handling for schema changes

- Fix pgtype.UUID usage in test files by properly converting string UUIDs to pgtype.UUID
- Update numericToFloat to use pgtype.Float8 instead of pgtype.Numeric for DOUBLE PRECISION support
- Fix field name from WebURL to WebUrl to match current schema

These changes align with the recent community_rating type change to DOUBLE PRECISION
and ensure consistent type handling across the codebase.
