perf(api): add explicit Prisma selects on hot read paths

Replaces full model includes with field-scoped selects on the resource
list (listStaff) query. Avoids fetching large JSONB columns
(availability, valueScoreBreakdown) and unused scalar fields (aiSummary,
portfolioUrl, fte, resourceType, postalCode, etc.) when only
identity/rate fields are needed.

Adds RESOURCE_LIST_SELECT constant to packages/api/src/db/selects.ts
covering all fields actually consumed by ResourcesClient, FillOpenDemandModal,
EstimateWizard, EstimateWorkspaceDraftEditor, and ScenarioPlanner.
