Pure-Python helper that resolves a fusion.report's line_specs against
account_totals -> ordered list of report row dicts. Supports three spec
types: account_type_prefix (sum accounts by type), account_id (single
account, drill-downable), and compute='subtotal' (sum last N rows).
Comparison-period support: variance_pct computed automatically when
comparison_totals are supplied.

Persistent definition of a Fusion financial report. Each report (P&L,
balance sheet, trial balance, GL) has one row in fusion.report holding
its metadata + line specs (stored as JSON for layout flexibility).
V19 conventions: models.Constraint inline, no _sql_constraints. Per-
company uniqueness on (company_id, code).
