Closes #51

What

Fixes paging in GetManyClients (ClientsGrpcService.cs) per .kiro/specs/must-fix-51/spec.md.

• request.Page is now a 1-based page number (default 1).
• request.Skip is reused as the page size (default DefaultPageSize = 10).
• Offset is (page - 1) * pageSize, so consecutive pages no longer overlap.
• NextUrl is built from the same page/pageSize variables (page={page+1}&skip={pageSize}).
• Total is set on every response; NextUrl is emitted only when more rows exist beyond the window.

Proto

Comment-only edit to the page/skip field docs in client.proto to match the new meaning. No field added, removed, or renumbered — no schema change, no client regen forced.

Tests

New MicroZen.Api.Test/Services/ClientsGrpcServiceTests.cs (EF Core InMemory), seeding 25 clients:

1. Page 1 returns the first 10 by name; Total=25; NextUrl has page=2, skip=10.
2. Page 2 returns 11–20 and is disjoint from page 1; NextUrl has page=3.
3. Last page (page 3) returns 21–25 with no NextUrl.
4. Defaults (Page=0, Skip=0) behave as page 1, size 10.
5. Total is set on every response.

The test project aliases the transitive MicroZen.OAuth2 reference so the duplicated MicroZen.Grpc.V1 proto types resolve unambiguously to MicroZen.Api.

Scope / notes

• Paging only. The searchTerm filter bug is Client search filters on the whole request object, not the search term #50 and is untouched here.
• Semantic change to skip (now page size) is a wire-contract change, but the old behaviour produced overlapping windows, so there is no correct caller to preserve.

Verification (from the worktree)

• npx nx affected -t lint test build — green (16/16 tests).
• dotnet test core/csharp/MicroZen.Core.sln — green (16/16).
• npx nx format:check passes for all files in this change; the only flags are pre-existing tracked spec .md files and untracked local .nx/ data, both outside GetManyClients paging defaults are wrong and NextUrl double-counts #51's scope.

Reviewed against .kiro/specs/must-fix-51/spec.md. All acceptance points met.

Paging logic (ClientsGrpcService.cs)

• page is a 1-based page number, default 1. ✅
• skip reused as page size, default DefaultPageSize = 10. ✅
• offset = (page - 1) * pageSize, fed to .Skip(skip); .Take(pageSize). ✅
• NextUrl rebuilt from the same page/pageSize vars (page={page+1}&skip={pageSize}), consistent with the window. ✅
• hasMore = skip + clients.Count < total correctly suppresses NextUrl on the last page (replaces the old no-op anyMoreClients guard). ✅
• Total set on every response, not only when a next page exists. ✅

Proto (client.proto) — comment-only edits to page/skip docs; no field added, removed, or renumbered. No schema break. ✅

Tests (ClientsGrpcServiceTests.cs, 25 seeded clients)

• Page 1 → first 10 by name, Total=25, NextUrl has page=2/skip=10. ✅
• Page 2 → clients 11–20, asserted disjoint from page 1. ✅ (proves non-overlapping)
• Last page (3) → 21–25, no NextUrl. ✅
• Defaults (Page=0,Skip=0) behave as page 1 size 10. ✅
• Total set on every response. ✅

Scope — the searchTerm $"%{request}%" bug (#50) is left untouched in the method; the diff does not modify those lines. ✅

CI — gh pr checks 86: dotnet pass, main pass. ✅

No change requests.

ALL-CLEAR -- PR #86 fully satisfies .kiro/specs/must-fix-51/spec.md (1-based page, skip-as-page-size, offset=(page-1)*pageSize, consistent NextUrl, Total always set, proto comment-only, paging-only scope with #50 untouched, non-overlapping page1/page2 tests) and CI checks are green (dotnet + main).
