"""Force re-import of the engagement mail templates on 19.0.2.4.0.

The mail templates ship in `<data noupdate="1">` so support's later
tweaks (different reply-to, custom signature, etc.) aren't blown away
by every routine module upgrade. The flip side: a structural change
to the template body in our own XML is silently skipped — the next
`-u` reads the new XML but Odoo refuses to overwrite the existing
row because of the noupdate flag.

This release introduces the 3-section email layout (Original Request /
Our Reply / Summary) and we DELIBERATELY want it to land. So this
pre-migration deletes the existing template records + their
ir_model_data anchors BEFORE the upgrade's data load runs. The XML
import then re-creates them with the new body_html.

Pre-migration > post-migration here because data load happens between
the two. If we deleted in post-migration, the data load would already
have skipped the update — too late.
