Some checks failed
Release / build (windows-latest) (push) Has been cancelled
feat: add Budget and Adjustments pages with full functionality
Budget: monthly data grid with inline-editable planned amounts per
category, actuals from transactions, difference coloring, month
navigation, and save/apply/delete budget templates.

Adjustments: split-panel CRUD for manual adjustment entries.

Both features include FR/EN translations and follow existing
service/hook/component patterns.

- `read_file_content` — encoding-aware file read (UTF-8, Windows-1252, ISO-8859-15)
- `hash_file` — SHA256 for duplicate detection
- `detect_encoding` — smart encoding detection
- `get_file_preview` — first N lines preview
- `pick_folder` — native folder picker dialog
### Database (11 tables)
**Core:** transactions, categories, suppliers, keywords
**Import:** import_sources, imported_files
**Planning:** budget_entries, budget_templates, adjustments, adjustment_entries
**User:** user_preferences (key-value: language, theme, currency, date_format)

db, transactionService, categoryService, importSourceService, importedFileService, dashboardService, reportService, categorizationService, userPreferenceService
### Hooks (7)
useDashboard, useTransactions, useCategories, useReports, useImportWizard, useImportHistory, useUpdater
### CI/CD
- GitHub Actions release workflow on `v*` tag push
- Windows-only (Ubuntu/macOS commented out)
- NSIS + MSI installers
- Tauri updater with signed artifacts (`latest.json` in release assets)
- Signing keys required: `TAURI_SIGNING_PRIVATE_KEY` + `TAURI_SIGNING_PRIVATE_KEY_PASSWORD` secrets
### Infrastructure Done
- Tailwind CSS v4 with CSS custom properties (light mode palette: blue primary, cream background, terracotta accent)
- react-i18next with FR default + EN
- lucide-react icons
- useReducer state management pattern (no Redux)
- Parameterized SQL queries ($1, $2...)
- Seeded categories & keywords in migration

## Pending / Not Yet Started
### Updater Setup (One-time manual)
- [ ] Generate signing keys: `npx tauri signer generate -w ~/.tauri/simpl-resultat.key`
- [ ] Add GitHub Secrets: `TAURI_SIGNING_PRIVATE_KEY`, `TAURI_SIGNING_PRIVATE_KEY_PASSWORD`
- [ ] Replace `REPLACE_WITH_PUBLIC_KEY` in `tauri.conf.json` with contents of `.key.pub`
- [ ] Tag + push a release to verify `latest.json` appears in assets
### Features Not Implemented
- **Dark mode** — CSS variables defined but no toggle yet
- **Data export** — Reports page has an "Export" button label but no implementation
- **Transaction splitting** — Schema supports it (`parent_transaction_id`) but no UI
- **Supplier management UI** — Suppliers table exists, auto-linked during import, but no dedicated management page
- **User preferences UI** — Settings page exists but doesn't yet expose language/theme/currency/date format preferences (language toggle is in sidebar)
- **Multi-platform builds** — Ubuntu and macOS targets commented out in release workflow
- **Backup / restore** — No database backup feature yet
