fix(plating): parse Fischerscope .doc/.docx/RTF dropped on the cert form

The cert form's x_fc_local_thickness_pdf field only stored the upload; only
the Issue Certs wizard parsed it. Add create/write hooks on the jobs-side
fp.certificate that, when a NON-PDF is written to that field, run the wizard's
parser: readings -> thickness_reading_ids, header metadata -> x_fc_thickness_*,
microscope image (RTF) -> x_fc_thickness_image_id, then relocate the source to
x_fc_local_thickness_evidence_id and clear the PDF field (mirrors the wizard's
non-PDF end state). Real PDFs pass through untouched for the page-2 merge.
Re-entry guarded via the fp_skip_thickness_parse context flag. Bump jobs
19.0.11.3.0.

Deployed + verified on entech: CoC-30065 (.doc) back-filled to 3 readings +
metadata (operator BK) + extracted microscope image, renders inline (242KB);
PDF cert CoC-30040-02 correctly left untouched.
