The previous fix swapped t-field -> t-esc so the QWeb error stopped,
but the report still printed blank. Root cause: Odoo looks up the
report data model via env['report.<report_name>'], but our model was
named 'report.fusion_plating_jobs.report_fp_job_margin' while the
action's report_name is 'fusion_plating_jobs.report_fp_job_margin_template'.
The model lookup missed, _get_report_values never fired, and the
template rendered with no 'rows' in scope — empty foreach -> empty
page.
Renamed the model to report.fusion_plating_jobs.report_fp_job_margin_template.
Verified: PDF size jumped from 1229 bytes (blank) to 125880 bytes
(fully populated). HTML now contains 'Job Margin', 'Step Breakdown',
and the actual WO name.
