Pure-Python helper that, given an account_id and a date range, fetches
posted account.move.line records and returns a flat list of dicts ready
for the drill-down OWL dialog. Used by the engine's drill_down() method.

Made-with: Cursor
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.

Made-with: Cursor
Pure-Python helper for FX conversion at report end-date. Handles direct
rates, inverse rates, and fallback to most-recent-rate-on-or-before.
fetch_rates() pulls from res.currency.rate using the same
1/rate inversion convention Odoo uses internally.
Made-with: Cursor
Three service modules with no Odoo dependencies:
- date_periods: fiscal year/month/quarter bounds + comparison derivation
- account_hierarchy: parent-child tree walker with type filtering
- totaling: move-line aggregation primitives
18 unit tests covering edge cases (December rollover, Feb 29, fiscal-
year-before-start, balance check tolerance).
