Pass preprocessed_columns directly to seq_of_component_size

[noa-starkware]

Summary

• seq_of_component_size now takes &HashMap<PreProcessedColumnId, Var> instead of &mut CompositionConstraintAccumulator
• The function only needs the preprocessed columns map — passing the full accumulator was over-broad
• All 17 call sites updated to pass &acc.preprocessed_columns

Stacks on #448. Part of audit cleanup (ilya/audit2 TODO comments).

PR Summary

Low Risk
Low risk refactor that narrows a helper’s inputs and updates call sites; main risk is mismatched preprocessed-column plumbing causing incorrect seq_* lookup at runtime.

Overview
Refactors seq_of_component_size (in both cairo_air and circuit_air) to take only &HashMap<PreProcessedColumnId, Var> instead of the full CompositionConstraintAccumulator, and switches internal lookups to use the passed map.

Updates all affected components/gates to call seq_of_component_size(context, component_data, &acc.preprocessed_columns) so the helper no longer requires (or implies) mutable access to the accumulator.
