feat(grn): add update functionality for draft GRNs and support document-level discounts

- Implemented Update method in GrnsController to allow editing of draft GRNs.
- Enhanced CreateGrnRequest to include an optional totalDiscount property.
- Updated GrnService to handle GRN updates, including validation and line item processing.
- Modified NewGrnPage to support editing existing GRNs and applying document-level discounts.
- Improved UI in NewItemPage and GrnDetailPage for better user experience.
- Added search functionality to Select component for improved item selection.

 > **Fields not explicitly spelled out verbatim in GL's reference** (its own numeric-id column names for `ChequeBook`/`ChequePage`, and `ReceivedCheque`'s JSON id field) are built from the request-body field names GL *does* document plus this project's consistent `<entity>Id` convention, flagged in `types/general-ledger.ts`'s comments — `chequeNo`/`chequeBookNo` (both explicitly documented as the identifying route values) are used for keys/URLs throughout instead, sidestepping the guess entirely wherever possible. **Not done:** live smoke test against a running GL instance — this entire module is unverified against real Cheque Management data. Verified: `tsc --noEmit`/`eslint` clean on every touched file; `npm run build` compiles successfully (Turbopack), its full-project TypeScript check still blocked only by the pre-existing, unrelated `hrm/employees/[id]` error.
 >
 > **2026-07-20 (3) — General Ledger report corrected again: `accountId` dropped entirely, not just made direct-entry.** The GL service's own contract changed (confirmed against its updated docs): `GeneralLedger`'s `accountId` is now optional, and the *omitted* case is the real General Ledger (every postable account together, each with its own running balance, sorted by `accountCode` then `entryDate`) — supplying `accountId` is a separate "Account Ledger" (single account + descendants) mode this page doesn't use. Superseding the same-day entry above: the numeric Account ID input is gone, `reportsApi.generalLedger()` dropped the `accountId` parameter, and the page now fetches on `periodStart`/`periodEnd` alone with sensible defaults — auto-fetching on page load like every other report screen (this also resolves the earlier-reported "no network call when landing on the page," which was the now-removed account-required gate). Result rows are grouped into per-account sections in the table (a header row wherever `accountCode` changes), matching the API's per-account running-balance reset. No frontend change was needed for the same-day `BalanceSheet` response addition (a synthetic `"Current Year Earnings"` equity row) — the existing generic row renderer already displays whatever rows come back. Verified: `tsc --noEmit` clean, `npx eslint app/dashboard/ledgers lib/api/general-ledger.ts` produces zero output, `npm run build` succeeds.
+>
+> **2026-08-05 — Cheque Management status/type fields were rendering as raw integers, not names (user-reported + confirmed with GL's own `06_Enums_Reference.md`).** That doc's key fact: GL has no global `JsonStringEnumConverter`. A JSON-**body** enum field (e.g. the Issue-cheque form's `payeeType`) is independently declared `string` server-side and parsed via `Enum.TryParse`, and a query-string enum filter binds natively by name — both already correct here, unaffected. But `ChequeBook.status`, `ChequePage.issueStatus`, `ChequePage.payeeType`, `ReceivedCheque.receivedFromType`, and `ReceivedCheque.status` are genuine enum-typed properties on GL's own **response** DTOs, backed by real `integer` DB columns — with no converter, GL's JSON serializes each one as its raw number (`1`/`2`/`3`/...), not its name. This wasn't just a cosmetic label bug: every list badge, the dialogs' status-based available-actions logic, and any `===` comparison against this frontend's own string enums (`ChequeBookStatus.Active`, etc.) would have silently mismatched against these numbers. Fixed at the API boundary, not scattered across every consumer: added five `*_BY_CODE` lookup maps to `types/general-ledger.ts` (one per affected field, keyed by the exact integers `06_Enums_Reference.md` documents), and applied them in `lib/api/general-ledger.ts` via new `Raw*` types (describing GL's actual `number`/`number | null` response shape for these fields) plus `mapChequeBook`/`mapChequePage`/`mapReceivedCheque` helpers wired into every `chequeBooksApi`/`chequePagesApi`/`receivedChequesApi` method that returns one — so every page/dialog/badge map keeps working against the same string values as before, unchanged. Cross-checked every other enum in that doc's "Persisted enums" table against this frontend (`JournalEntryStatus`/`PeriodStatus`/`TaxCalculationBasis`/`TaxAppliesTo`/`DepreciationMethod`/`FixedAssetStatus`/`AuditCategory`/`AuditAction`) — none are consumed anywhere in this app, confirming Cheque Management was the complete fix, not a partial one. Verified: `tsc --noEmit`/`eslint` clean on both touched files.

   a dialog is supposed to stay narrow, this complaint was about full-page create forms only.
+- [x] **Cheque Management status/type fields were displaying raw integers, not names (2026-08-05, user-reported + confirmed live) — fixed by mapping GL's response integers to this frontend's string enums at the API boundary.** User supplied GL's own `06_Enums_Reference.md`: GL has no global `JsonStringEnumConverter`, so while a JSON-**body** enum field is independently declared `string` server-side (and a query-string enum filter binds natively by name — both already correct here, unaffected), a real enum-typed **response** DTO property serializes as its raw underlying integer with no converter to turn it back into a name. `ChequeBook.status`, `ChequePage.issueStatus`, `ChequePage.payeeType`, `ReceivedCheque.receivedFromType`, and `ReceivedCheque.status` are exactly that — genuine DB-backed enum properties on GL's response DTOs — so every one of them was arriving as `1`/`2`/`3`/... instead of `"Active"`/`"Issued"`/`"Supplier"`, silently breaking every `===` comparison this frontend does against its own string enums (list badges, the create-form's own `<Select>` values, and both dialogs' status-based available-actions logic), not just the visible label. Added five `*_BY_CODE` lookup maps to `types/general-ledger.ts` (`CHEQUE_BOOK_STATUS_BY_CODE`/`CHEQUE_PAGE_ISSUE_STATUS_BY_CODE`/`PAYEE_TYPE_BY_CODE`/`RECEIVED_FROM_TYPE_BY_CODE`/`RECEIVED_CHEQUE_STATUS_BY_CODE`), keyed by the exact integer values `06_Enums_Reference.md` documents. Applied them in `lib/api/general-ledger.ts` via new `Raw*` types (describing what GL's JSON for these fields actually is: `number`/`number | null`) and `mapChequeBook`/`mapChequePage`/`mapReceivedCheque` helpers, wired into every `chequeBooksApi`/`chequePagesApi`/`receivedChequesApi` method that returns one of these shapes — the translation happens once, at the API boundary, so every existing page/dialog/badge map keeps comparing against the same string enum values as before and needed zero changes itself. Checked every other enum in `06_Enums_Reference.md`'s "Persisted enums" table (`JournalEntryStatus`/`PeriodStatus`/`TaxCalculationBasis`/`TaxAppliesTo`/`DepreciationMethod`/`FixedAssetStatus`/`AuditCategory`/`AuditAction`) against this frontend — none are consumed anywhere (no Journal Entry/Fiscal Period/Tax Code/Fixed Asset/Audit Log UI exists here), so Cheque Management is the complete fix, not a partial one. Verified: `tsc --noEmit`/`eslint` clean on both touched files.
