refactor(selling, buying): make raw SQL portable to PostgreSQL

Convert the MariaDB-only raw `frappe.db.sql` in the Selling and Buying
modules to the cross-database query builder / ORM, and fix the few
non-portable constructs that remain. Every change is a no-op on MariaDB
(identical rendered SQL / identical results) and only brings PostgreSQL —
which is standards-strict where MySQL is lax — in line.

Patterns addressed in these modules:

- Strict GROUP BY — PostgreSQL rejects SELECTing a non-aggregated column
  that isn't functionally dependent on the grouped key. Sales Order
  Analysis, Sales Analytics, Purchase Order Analysis and Procurement
  Tracker now group by the PK (1:1 with the existing key, so no behaviour
  change) or aggregate genuinely-independent columns.
- App clock vs DB clock — Sales Order Analysis computed delay against the
  database CURRENT_DATE, which differs from the app's today by a day when
  the DB runs a different timezone; switched to `nowdate()` (deterministic,
  identical on both DBs).
- Portable date math / functions — DATEDIFF and friends via the db-aware
  query-builder functions.
- Raw SQL → query builder for the remaining self-contained selling/buying
  reads (POS item search, customer naming suffix, packing-items
  availability, customer credit/acquisition reports).

Part of the staged MariaDB↔PostgreSQL parity rollout (module 1 of 9).
