le king fu	afc338b564	feat(balance): extend balance.service with snapshots + lines (simple kind) ... Adds the snapshots + lines section of the balance service for Issue #146 (Bilan #1b). Simple-kind only — quantity / unit_price are forced to NULL both at the SQL CHECK level (already in v9) and at the service level (`upsertSnapshotLines` validates ahead of time). Priced-kind upsert lands in #140. New service exports: - listSnapshots / getSnapshotByDate / getSnapshotById / getPreviousSnapshot - createSnapshot (throws snapshot_date_taken when UNIQUE per date violated so the UI can redirect to edit mode) - updateSnapshot / deleteSnapshot (cascade lines via FK) - listLinesBySnapshot / upsertSnapshotLines (rewrite-all strategy) New BalanceErrorCode entries: snapshot_date_required, snapshot_date_taken, snapshot_not_found, snapshot_value_invalid, snapshot_priced_unsupported. New shared types: BalanceSnapshot, BalanceSnapshotLine. 22 new vitest cases cover: invalid-date guards, unique-per-date violation, simple-kind null invariant on inserts, NaN/Infinity rejection, clear+rewrite line semantics, getPreviousSnapshot strict-before ordering.

le king fu	58d3c86336	feat(balance): add balance.service CRUD section + tests ... Adds the TypeScript service layer for the Bilan feature, scoped to Issue #138 (Bilan #1a) — categories + accounts CRUD only. Snapshots, snapshot lines, transfers and price-fetching land in subsequent issues. The service uses `getDb()` + tauri-plugin-sql directly per project convention (96 occurrences across 15 services). No new Tauri commands introduced — the only future Rust commands are `compute_account_return` (Issue #142) and `fetch_price` (Issue #144). API surface: - listBalanceCategories / getBalanceCategory / createBalanceCategory / updateBalanceCategory / deleteBalanceCategory (with seed + has-accounts guards) - listBalanceAccounts (excludes archived by default) / getBalanceAccount / createBalanceAccount (CAD-only at MVP) / updateBalanceAccount / archiveBalanceAccount / unarchiveBalanceAccount (soft delete) Typed errors via BalanceServiceError + BalanceErrorCode union so the UI can render distinct i18n messages. Domain types added under `src/shared/types/index.ts`: BalanceCategoryKind, BalanceCategory, BalanceAccount, BalanceAccountWithCategory, BALANCE_CURRENCY_CAD. 19 vitest cases cover: ordering, kind validation, seed protection, linked-account guard, currency rejection, missing-category lookup, soft delete + restore round-trip, symbol/notes normalization.
