Deepen Account + Stock modules significantly

Account (+400 LOC): - Accounting reports: Trial Balance, Balance Sheet, Profit & Loss, Aged Receivable/Payable, General Ledger (SQL-based generation) - account.report + account.report.line models - Analytic accounting: account.analytic.plan, account.analytic.account, account.analytic.line models - Bank statement matching (button_match with 1% tolerance) - 6 default report definitions seeded - 8 new actions + 12 new menus (Vendor Bills, Payments, Bank Statements, Reporting, Configuration with Chart of Accounts/Journals/Taxes) Stock (+230 LOC): - Stock valuation: price_unit + value (computed) on moves and quants - Reorder rules: stock.warehouse.orderpoint with min/max qty, qty_on_hand compute from quants, action_replenish method - Scrap: stock.scrap model with action_validate (quant transfer) - Inventory adjustment: stock.quant.adjust wizard (set qty directly) - Scrap location seeded Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
