gsinghpal 6e945dea95 feat(fusion_accounting_bank_rec): pattern + precedent models for behavioural learning
Adds the foundation for AI confidence scoring:
- fusion.reconcile.pattern: per-(company, partner) aggregate profile
  (volume, cadence, preferred matching strategy, memo signature,
  write-off habits) — recomputed nightly from precedents.
- fusion.reconcile.precedent: per-historical-decision memory holding
  full feature vector + outcome, used by precedent_lookup for KNN
  scoring of new bank lines.

Includes ACL rows for fusion accounting user (read) and admin (CRUD)
groups. Manifest bumped to 19.0.1.0.1.

Note: switched the pattern uniqueness rule from the deprecated
_sql_constraints attribute to models.Constraint (Odoo 19 native API)
so the unique(company_id, partner_id) is actually enforced at the
PG level — _sql_constraints is silently ignored in 19.
