chore(deps): upgrade @sdcorejs/utils to 1.2.3 on every line (#64) Move the runtime dependency from 1.1.4 to 1.2.3 in v19 (canonical) and roll it out to v20/v21/v22 and the showcase. 1.2.3 is the first 1.2 release whose legacy date helpers accept backend timestamps with sub-millisecond fractions and colon-less offsets again. With 1.2.0-1.2.2, Core Legacy rendered every such table date as "--". Lockfiles change only the @sdcorejs/utils entry (1.2.3 drops its optional rxjs peer). Each lockfile keeps its original indentation, v19/v20/v21 and the showcase were installed with --legacy-peer-deps, and v22 with a clean install, all on Node 22.22.3. Adapting to the 1.2 contract without changing @sdcorejs/angular behaviour: - normalizeAsync now returns a structural subscribable, which toSignal and defer/combineLatest reject. auth.service and sd-breadcrumb adapt MaybeAsync to a real Observable (same adapter as Core Legacy), so re-emitting sources stay live. - getNestedValue returns T | undefined; TableFormatService types cell values through one documented SdTableCellValue alias, as Core Legacy does. - BrowserUtilities.upload now rejects with FilePickerCancelledError on cancel or timeout instead of resolving empty. sd-upload-file no longer shows an error toast for it, SdApiService.upload() still resolves undefined without a request, and SdExcelService.upload() still resolves an empty result. Validation errors are unchanged. - MaybeAsync is now T | PromiseLike | SubscribableLike instead of including RxJS Observable. SubscribableLike does not accept an Observable of a narrower type: Observable for string | null | undefined, an Observable of a subtype, or an Observable of one union member. That broke consumer code such as the showcase's BehaviorSubject breadcrumb label. The public async slots (breadcrumb label, auth signout / changePassword / authInfo, layout sidebar / userInfo, permission loadPermissions / getToken) are typed MaybeAsync | Observable, which restores the 1.1.x acceptance, and internal resolveMaybeAsync calls pin their type argument. Regression specs cover each point, including typed (satisfies) configs that fail to compile against the unwidened types and a datetime pipe spec for microsecond timestamps. Docs for auth, layout, permission, breadcrumb and query-bar plus CHANGELOG [Unreleased] are updated. Verified: check:sync; tsc on v19/v20/v21/v22 and the showcase; v19 and v22 suites with coverage (5936/5936 each); v19 library build; test:scripts; eslint on the changed files reports nothing new.
