ci(fusion_accounting): add CI workflow scaffold + Phase 0 deferral note

Workflow structure is complete (path filters, matrix, services).
The 'Install Odoo 19' step is a TODO placeholder — the reproducible
Odoo-19 build environment is deferred to Phase 1 CI hardening.
Current Phase 0 test workflow is manual via ssh odoo-westin.
