New TurnKey Odoo version (19.0)

Install supported Odoo 19 Community from its official daily package channel with an exact package digest and bound repository key. Preserve the upstream payload while restoring its source-declared Trixie PDF dependency alternative in package control metadata.
Install Odoo's required patched wkhtmltopdf 0.12.6 series from an exact upstream package digest for PDF report rendering.
Bridge Odoo's stale python3-pypdf2 package dependency to Trixie's maintained python3-pypdf implementation without modifying Odoo's payload.
Use a non-superuser PostgreSQL application role and keep generated database and firstboot credentials out of process arguments and traces.
Add a non-mutating update check, v19 acceptance coverage, and README evidence crosswalk. Prepare supervised updates through the same verified, payload-preserving control correction used at build time.
Upgrade the base distribution to Debian 13 Trixie.
