fix(plugin-view): coerce i18n tab-label helpers to string (TS2322)

[os-zhuang]

What

useViewTabLabel() in ViewTabBar.tsx and the identical useViewLabel() in ManageViewsDialog.tsx returned the raw t() result. i18next types t() as string | object (it can resolve a key to an object), so the helper's return type was string | object.

That value is rendered directly as a React child and passed as aria-label at ~35 call sites, so vite build's declaration-generation (dts) pass emitted error TS2322: Type 'string | object' is not assignable to type 'ReactNode' (and to string | undefined for aria-labels).

Because plugin-view builds with vite build (no type-check gate), these did not fail the build — but they are real: if t() ever resolves a key to an object, React throws and white-screens. This is the known "i18n/expression value is string | object, rendered raw → white-screen" class.

Fix

Coerce the resolved value with String(v) and annotate the helper return type as string, in both helpers. Behavior-preserving for the normal (string) case.

Scope

The task named ViewTabBar.tsx; while verifying at the package level, the vite build dts pass surfaced the identical bug (22 TS2322s) in the sibling ManageViewsDialog.tsx — same copied helper, same root cause, same package. Fixed both so the package is clean of this class. Out of scope for the docs-build fix in #2718; tracked separately.

Verification

• pnpm --filter @object-ui/plugin-view build — before: TS2322 from both files; after: no TS2322 / error TS, declaration files build cleanly, ✓ built.
• eslint on both files reports only pre-existing warnings/errors (conditional hook, vars as any, Function type, setState-in-effect) — none introduced by this change.
