<objective>
Thread multi-signer state through the component tree so PreparePanel and FieldPlacer can consume signers data in Wave 2.

Purpose: Foundation wiring — DocumentPageClient is the state owner for signers (from Phase 14 schema) and unassignedFieldIds (for send-block validation). Without this, Wave 2 plans cannot receive or modify signer state.

Output: Updated DocumentPageClient with signers + unassignedFieldIds state; server page fetching documents.signers; PdfViewerWrapper passing new props through.

<!-- Key types and contracts the executor needs. Extracted from codebase. -->

From src/lib/db/schema.ts:
```typescript
export interface DocumentSigner {
  email: string;
  color: string;
}

export interface SignatureFieldData {
  id: string;
  page: number;
  x: number;
  y: number;
  width: number;
  height: number;
  type?: SignatureFieldType;
  signerEmail?: string;
}

export function isClientVisibleField(field: SignatureFieldData): boolean;
export function getFieldType(field: SignatureFieldData): SignatureFieldType;
export function getSignerEmail(field: SignatureFieldData, fallbackEmail: string): string;
```

From DocumentPageClient.tsx (current props):
```typescript
interface DocumentPageClientProps {
  docId: string;
  docStatus: string;
  defaultEmail: string;
  clientName: string;
  agentDownloadUrl?: string | null;
  signedAt?: Date | null;
  clientPropertyAddress?: string | null;
}
```

From PdfViewerWrapper.tsx (current props):
```typescript
{
  docId: string;
  docStatus?: string;
  onFieldsChanged?: () => void;
  selectedFieldId?: string | null;
  textFillData?: Record<string, string>;
  onFieldSelect?: (fieldId: string | null) => void;
  onFieldValueChange?: (fieldId: string, value: string) => void;
  aiPlacementKey?: number;
}
```

From FieldPlacer.tsx (current props — FieldPlacerProps interface at line 155):
```typescript
interface FieldPlacerProps {
  docId: string;
  pageInfo: PageInfo | null;
  currentPage: number;
  children: React.ReactNode;
  readOnly?: boolean;
  onFieldsChanged?: () => void;

  textFillData?: Record<string, string>;
  onFieldSelect?: (fieldId: string | null) => void;
  onFieldValueChange?: (fieldId: string, value: string) => void;
  aiPlacementKey?: number;
}
```

From PreparePanel.tsx (current props):
```typescript
interface PreparePanelProps {
  docId: string;
  defaultEmail: string;
  clientName: string;
  currentStatus: string;
  agentDownloadUrl?: string | null;

  textFillData: Record<string, string>;
  selectedFieldId: string | null;
  onQuickFill: (fieldId: string, value: string) => void;
  onAiAutoPlace: () => Promise<void>;
}
```

From server page.tsx:
```typescript
// doc fetched via db.query.documents.findFirst — has all document columns including signers
const doc = await db.query.documents.findFirst({ where: eq(documents.id, docId) });
// doc.signers is DocumentSigner[] | null (JSONB column from Phase 14)

    **server page.tsx:**
    - `doc` is already fetched via `db.query.documents.findFirst` which returns all columns including `signers`. Pass `doc.signers` to DocumentPageClient as `initialSigners`:
      ```
      initialSigners={doc.signers ?? []}
      ```

    **DocumentPageClient.tsx:**
    - Import `DocumentSigner` from `@/lib/db/schema`
    - Add `initialSigners: DocumentSigner[]` to `DocumentPageClientProps`
    - Add state: `const [signers, setSigners] = useState<DocumentSigner[]>(initialSigners);`
    - Add state: `const [unassignedFieldIds, setUnassignedFieldIds] = useState<Set<string>>(new Set());`
    - Pass to PreparePanel: `signers={signers}`, `onSignersChange={setSigners}`, `unassignedFieldIds={unassignedFieldIds}`, `onUnassignedFieldIdsChange={setUnassignedFieldIds}`
    - Pass to PdfViewerWrapper: `signers={signers}`, `unassignedFieldIds={unassignedFieldIds}`
    - No other changes to existing props or callbacks

    - Do NOT implement rendering changes yet (that is Plan 03) — just accept the props

    All three files: add the two new optional props and pass them through. No rendering or behavioral changes.
