Fix all indentation errors - remove leading spaces from branches_sample and diagnostics_sample

Fixed indentation errors on lines 88 and 123. Both branches_sample and diagnostics_sample variables were accidentally indented inside the with gr.Blocks() block. Removed all leading spaces so these variables are declared at module level as intended. This completes the indentation fix for all sample data variables.
