fix(selectors): paginate SharePoint sites and lists

[BillLeoutsakosvl346]

Summary

• replace the silent ten-page SharePoint site/list drain with cursor-backed Microsoft Graph pagination
• expose provider-side site search while keeping list search local
• preserve direct site/list detail hydration, credential bindings, abort propagation, and Graph destination validation
• keep Excel consent issue fix(microsoft-excel): decide SharePoint site discovery consent model #7197 separate and out of scope

Type of Change

• Bug fix
• New feature
• Breaking change

Testing

• bun run --cwd apps/sim test lib/selectors/server/providers/sharepoint.test.ts lib/selectors/server/providers/microsoft.test.ts lib/selectors/manifest.test.ts hooks/queries/selectors.test.tsx — 4 files, 28 tests passed
• SharePoint provider coverage verifies site/list cursor continuation, site search forwarding, invalid Graph destination rejection, and existing direct detail hydration
• bun run check:api-validation:strict — passed
• bun run check:fork-dependent-coverage — passed
• bun run check:client-boundary — passed
• scoped Biome check and git diff --check — passed
• bun run --cwd apps/sim type-check currently fails in unrelated files on the staging base: workflow-output-selector types and the new color utility export
• live Microsoft Graph validation was not performed because no native SharePoint tenant credential was available

Greptile Summary

This PR replaces SharePoint’s bounded server-side page draining with cursor-backed Microsoft Graph pagination while preserving direct detail hydration and credential handling.

• Marks SharePoint site and list selectors as paginated.
• Forwards provider-side search for sites while retaining local filtering for lists.
• Validates continuation URLs against the Microsoft Graph origin and original resource pathname.
• Adds coverage for cursor continuation, search forwarding, destination rejection, and detail hydration.

Confidence Score: 5/5

The PR appears safe to merge with no concrete correctness or security failures identified.

Cursor pagination integrates with the existing selector accumulation and local-filtering behavior, while continuation URLs are constrained to Microsoft Graph and the original collection pathname.

Important Files Changed

Filename	Overview
apps/sim/lib/selectors/manifest.ts	Enables pagination for SharePoint sites and lists and provider-backed search for sites, consistently with selector client behavior.
apps/sim/lib/selectors/server/providers/sharepoint.ts	Replaces bounded page draining with validated one-page cursor requests while retaining credential, abort, filtering, and detail behavior.
apps/sim/lib/selectors/server/providers/sharepoint.test.ts	Adds focused coverage for site/list pagination, site search forwarding, cross-resource cursor rejection, and existing detail hydration.
