Migrate `actionItemSlaApi` and `actionItemTemplateApi` to `apiClient`

[imuniqueshiv]

Problem

SLA and action-item template services import raw axios instead of apiClient, missing shared interceptors and base URL handling.

What should be changed

• Refactor both modules to use apiClient.
• Verify SLA Compliance and Action Item Templates pages still work.
• Add service-level tests (complements [BUG]: recurringActionItemApi imports a non-existent ./apiClient; participantContributionApi bypasses apiClient #2574 for other modules).

Expected outcome

Template/SLA API calls use the standard client stack.

Main files/areas likely affected

client/src/services/actionItemSlaApi.js, client/src/services/actionItemTemplateApi.js, client/src/pages/SlaCompliance.jsx, client/src/pages/ActionItemTemplates.jsx

Why it matters

Part of consolidating HTTP access before program close.
