Fix Quick BaseEntity BoxLang metadata compatibility

[elpete]

Summary

• add BoxLang-specific regression tests for metadata parsing in BaseEntity metadata inspection
• port BoxLang compatibility logic from BackStage-Ops into Quick BaseEntity metadata handling
• normalize persistent metadata values when surfaced as strings/annotations

Changes

• support accessors metadata surfaced under localMetadata.annotations.accessors
• derive child discriminator metadata from the parent entity reference metadata
• use available local/original metadata function arrays for relationship detection
• read persistent from property annotations and coerce to boolean when needed

Validation

• box run-script format
• attempted to run targeted integration specs, but local HTTP test runner was unavailable in this shell environment (connection refused on 127.0.0.1:60299)
