Simplify the recently modified code in the monolith worktree for FHIR-2182 server-side pagination (hook layer).

Files to simplify:
- /Users/USER/workspace/doctolib/worktrees/doctolib/fhir-2182_server-side-pagination-hook/packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts
- /Users/USER/workspace/doctolib/worktrees/doctolib/fhir-2182_server-side-pagination-hook/packages/@doctolib/national-health-records/src/variants/types.ts

Context:
- The hook adds a page parameter to useSearchDocuments's returned async function
- PAGE_SIZE=20, slice after React Query cache lookup
- currentPage returned in all paths
- TypeScript strict mode, no eslint-disable allowed, no any

Please read the files and identify any simplifications for clarity and maintainability while preserving all functionality. The test file should NOT be simplified — only the two source files listed above.

I'll analyze the two files for simplification opportunities while preserving functionality.

I have read both files. Let me analyze for simplification opportunities.

Analysis of useSearchDocuments.ts:

1. Repeated result-shape construction: Each return path constructs { data, total, status, ..., currentPage }. There's some duplication but each path has slightly different fields, so consolidating could hurt clarity.

2. Repeated slice computation: const start = (page - 1)  PAGE_SIZE and slice(start, start + PAGE_SIZE) appear twice. Could be extracted into a small helper for clarity.

3. Nested ternary-ish pattern: The error instanceof Error ? error.message : undefined is fine — it's a single ternary, not nested.

4. try/catch usage: The CLAUDE.md guideline mentions avoiding try/catch when possible, but here it's catching from fetchQuery which throws on retry exhaustion — the catch is necessary for the error-shape return.

5. Type cast appliedFilters as ServerFilters appears twice. Could be hoisted once but it's only 2 uses, so marginal.

6. The page parameter default in the public type is fine.

Analysis of types.ts:

1. The DmpServerFilters type is defined AFTER it's used in ServerFilters = BaseServerFilters & DmpServerFilters. This works in TypeScript due to hoisting but is awkward to read top-to-bottom. Move it before usage.

2. DocumentSearchOptions interface — check if used elsewhere (might be dead code, but not in scope of this simplification per session). Leave alone.

Let me make targeted, conservative simplifications:

1. Extract slicing logic into a small helper to remove duplication and clarify intent.
2. Reorder DmpServerFilters to be defined before ServerFilters for top-to-bottom readability.

Let me apply these changes.

Now for the hook, I'll extract a small helper for the page-slicing duplication. This is a clarity win since the slice logic appears twice and the comment about "slicing happens after the cache lookup" becomes more meaningful when the slice operation is a named function.

Summary

Applied conservative simplifications to the two source files for FHIR-2182 server-side pagination hook layer.

File 1: /Users/USER/workspace/doctolib/worktrees/doctolib/fhir-2182_server-side-pagination-hook/packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts

Change: Extracted a small sliceForPage<T> helper to remove the duplicated (page - 1) * PAGE_SIZE slicing logic that appeared in both the mocked and live-cache return paths.

Why:
- DRY: removes two identical inline computations.
- Names the operation, which makes the cache-key comment ("slicing happens after the cache lookup") self-evident at the call sites.
- Generic over T, so it preserves the inferred document types in both branches without any cast.
- Top-level function keyword with explicit return type, per project conventions.

File 2: /Users/USER/workspace/doctolib/worktrees/doctolib/fhir-2182_server-side-pagination-hook/packages/@doctolib/national-health-records/src/variants/types.ts

Change: Reordered DmpServerFilters to be defined before ServerFilters (which composes it via BaseServerFilters & DmpServerFilters).

Why: TypeScript hoists type aliases so the original order compiled fine, but reading top-to-bottom is clearer when components are declared before the composed type. No functional change.

What was deliberately left alone

- The repeated { data: [], total: 0, status, currentPage } return shapes — each path differs in status, message, and code. Consolidating into a builder would obscure rather than clarify.
- The try/catch — necessary to convert fetchQuery's thrown retry-exhausted error into the explicit error-shape return contract.
- The appliedFilters as ServerFilters casts — only two occurrences, and hoisting would require re-typing the parameter, which changes the public signature.
- The error instanceof Error ? error.message : undefined — single ternary, not nested; idiomatic and clear.
- useSearchDocuments.test.ts — out of scope per instructions.

Verification

- TypeScript --noEmit against the package config: zero errors in the two modified files (pre-existing monorepo errors elsewhere are unrelated).
- Jest: all 35 tests in useSearchDocuments.test.ts pass.
- Prettier: both files pass --check.
