Standardize terminology across query languages

[kmcginnes]

Description

This PR updates UI labels and translations to use more accurate and consistent terminology for each query language:

Gremlin:

• Changed "Attribute" → "Property" throughout the UI
• Updated styling panel titles to "Node Label Styling" and "Edge Label Styling"

openCypher:

• Changed "Edge" → "Relationship" to match Cypher conventions
• Changed "Edge Label" → "Relationship Type"
• Changed "Attribute" → "Property"
• Updated styling panel titles accordingly

SPARQL:

• Changed "Resource URI" → "Resource Id" for consistency
• Changed "Predicate URI" → "Predicate Id"
• Changed "Source/Target URI" → "Source/Target Id"
• Changed "Literal" → "Datatype Property" for semantic accuracy

UI Improvements:

• Widened the entity type selector in the tabular view (36 → 48 width units) to accommodate longer labels like "Relationship Type"

Test Updates:

• Fixed test expectations to match new terminology
• Added missing query engine setup in edge attributes test

Validation

• Updated tests
