[ENG-1290] Conditional Deps Utils

[JadeCara]

Ticket ENG-1290

Description Of Changes

🎯 As a user, I want to specify conditions that must be true to create manual tasks, which check the request data, so that I can create tasks conditionally based on data in the request.

This PR adds some utils required for adding privacy request conditional dependencies

• Introspection utility: that will allow us the ability to retrieve the available fields from privacy request to impose conditions on. This allows us a clean way to report to the UI what the available queryable conditions are and verify data types up front. (Including configured custom privacy request and identity values)

Code Changes

• new src/fides/api/task/conditional_dependencies/privacy_request/util.py
• new tests/api/task/conditional_dependencies/privacy_request/test_util.py

Steps to Confirm

1. This change is new and not hooked up to anything. Tests should pass.

Greptile Summary

• Adds privacy request field introspection utilities to support conditional manual task creation, allowing dynamic discovery of available fields for imposing conditions on privacy request data
• Includes both a nested dictionary structure for UI consumption and a flat list for programmatic access, handling standard privacy request fields and custom fields from privacy center configurations
• Implements comprehensive test coverage with proper fixtures and validation of field extraction functionality across various privacy request field types

Important Files Changed

Filename	Overview
src/fides/api/task/conditional_dependencies/privacy_request/util.py	New utility module providing introspection capabilities for privacy request fields with database integration and config parsing
tests/api/task/conditional_dependencies/privacy_request/test_util.py	New test file with comprehensive coverage for field introspection utilities, including custom field handling tests

Confidence score: 4/5

• This PR is safe to merge as it adds new utilities without integration points, minimizing production risk
• Score reflects minor code quality issues: unused import/fixture in tests and broad exception handling in config parsing that could mask important errors
• Pay attention to the test file for cleanup of unused imports and consider more specific exception handling in the utility module
