feat(telephony/phase1): API layer — types + endpoints + Zustand stores

Phase 1 — API Layer Telephony

Pattern

Identique aux autres agents (community-manager, SEO) :

• axiosInstance partagé (src/config/axios)
• Headers X-USER-UID / X-User-UUID injectés automatiquement par le intercepteur + explicitement sur les routes qui le requièrent
• Endpoints centralisés (src/shared/api/endpoints/telephony-service/)
• Stores Zustand (src/shared/api/stores/telephony-service/)
• Types alignés sur les DTOs backend (src/shared/types/telephony/)

Types (6 fichiers)

• telephony-agent.types.ts — Agent, Wizard, enums
• telephony-call.types.ts — Call, CallResult + LABELS/COLORS
• telephony-campaign.types.ts — Campaign, Status + LABELS/COLORS
• telephony-prospect.types.ts — Prospect, ProspectStatus + LABELS/COLORS
• telephony-stats.types.ts — Stats, DayCount, StatsPeriod
• telephony-number.types.ts — PhoneNumber, Provider + LABELS

Endpoints (7 fichiers)

Couverture complète : CRUD + lifecycle (launch/pause/cancel) + import/export + wizard steps

Stores Zustand (7 fichiers)

• agent-store — CRUD + activate/deactivate + syncToVapi
• call-store — filtres (direction, result, dates, agentUid)
• campaign-store — CRUD + launch/pause/cancel/complete + export
• prospect-store — CRUD + importCsv + exportCsv + updateStatus
• stats-store — fetchStats (period/dates/agentUid)
• number-store — fetchByAgent/ByOwner + CRUD
• wizard-store — checkStatus + step1→step5 + complete
