The system now keeps only the most useful database indexes for internal record references, removing redundant ones. This should reduce unnecessary database overhead while preserving efficient lookups where they matter most.

Indexes on individual columns (module, name, model, res_id) have been dropped,
and the index on (model, name) was duplicated in a unicity constraint.  We have
kept two useful indexes, namely:
- a unique index on (module, name)
- a simple index on (model, res_id)

The Point of Sale loyalty module was reorganized and updated to use Odoo's newer internal framework. This keeps the loyalty feature easier to maintain and prepares it for future improvements without changing the core business offering.
