Fix IndentationError line 50: Add missing consent_events_sample declaration and correct indentation

ROOT CAUSE:
Line 50 had IndentationError because the dictionary literal { started with unexpected indentation without a proper variable assignment statement.

FIXES APPLIED:
1. Added consent_events_sample = [ on line 49 (column 0 - module level)
2. Corrected line 50 indentation to exactly 4 spaces (proper list item indentation)

This fix aligns with Python PEP 8 indentation standards and Gradio Blocks API requirements where data variables must be declared before the with gr.Blocks() context.
