- Fix thickness factor: now scales linearly (thickness * factor), not
multiplicatively. Default factor=1.0 means price scales 1:1 with mils.
- Fix batch_size: setup fee now multiplied by ceil(qty/batch_size) batches
- Fix hardcoded $ in price breakdown HTML: uses currency_id.symbol
- Add coating_config_id.certification_level to @api.depends
- Remove readonly on x_fc_receiving_status (placeholder until receiving module)
- Add currency_id to treatment list view for Monetary widget
