Mihir Kandoi cfa6d286ad fix(postgres): other-class parity fixes (case-folding & null-ordering) for merged queries
Parity sweep findings in queries already merged in develop:

- pos_invoice.py: serial_no return-match matched case-sensitively on Postgres (case-insensitive
  on MariaDB). Replaced the get_all or_filters lookup with a qb query that case-folds both sides
  via Lower() (no-op on MariaDB).
- controllers/queries.py + pick_list.py: the Locate()-based relevance ranking in link-query
  ORDER BY is case-sensitive on Postgres (Strpos) vs case-insensitive on MariaDB (Locate), so
  autocomplete order differed. Lower() both arguments so the ranking matches on both engines.
- crm/lead_conversion_time.py: "first contact" used ORDER BY communication_date LIMIT 1 read by
  index; a NULL date sorts first on MariaDB but last on Postgres, changing the result. Added
  `communication_date IS NOT NULL` so both engines return the earliest real contact date.

Verified on MariaDB and Postgres: test_pick_list 40/40, test_pos_invoice 26/26 on both engines.
