refactor(frontend): replace TaskDetails result record any types with typed models-#1402

[Rakshak05]

Description

This PR replaces broad Record<string, any>, any[], and dynamic any index signatures with explicit interfaces or unknown-safe record types in the TaskDetails component.

Specifically, it implements the following modifications in TaskDetails.tsx:

• Replaced inputs?: Record<string, any> with Record<string, unknown> in the Task interface.
• Replaced metadata?: Record<string, any> with Record<string, unknown> in the Finding interface.
• Imported and utilized EvidenceRecord and AssetServiceRecord from ../api for the evidence field in Finding and the services field in AssetSummaryEntry respectively.
• Replaced references?: Array<Record<string, any>> with Array<Record<string, unknown>> in the Finding interface.
• Explicitly typed the structured results object structure in TaskResult to define findings?: Finding[] and total_count?: number alongside rows?: Array<Record<string, unknown>>.
• Replaced the row: any mapper typing with row: Record<string, unknown> in the tableRows rendering paths.
