feat(fusion_accounting_bank_rec): 3 cron schedules + handler model

- cron_suggest (every 30min): warm AI suggestions for unreconciled lines
  that don't have a recent pending one
- cron_pattern_refresh (daily 02:00): recompute fusion.reconcile.pattern
  for each (company, partner) pair with precedents
- cron_mv_refresh (every 5min): REFRESH MATERIALIZED VIEW CONCURRENTLY
  using a dedicated autocommit cursor (REFRESH CONCURRENTLY can't run
  inside a regular Odoo transaction)

V19 note: ir.cron dropped the numbercall field, so the data XML omits
it (cron now repeats indefinitely as long as active=True).

Tests: 5 new TestFusionBankRecCron tests pass; full module suite is
0 failed / 0 errors of 123 logical tests on westin-v19.
