From ae8b7bdce14db6a7e7a27ffb24fd050840ad23dd Mon Sep 17 00:00:00 2001 From: nutcas3 Date: Fri, 1 May 2026 23:26:41 +0300 Subject: [PATCH] feat: Refactor profile handlers into modular core components with simplified operations - Split profile_handlers.go into profile_handlers_core.go, profile_handlers_management_core.go, and profile_handlers_management_delete.go - Simplify OrderProfileHandlerWithRepo with ICCID/IMSI-only validation and "downloaded" state - Remove webhook and message queue notifications from order handler - Add UpdateProfileHandler with state validation for downloaded/activated/deactivated/expired - Add DeleteProfileHandler with existence --- .../internal/handlers/profile_handlers.go | 236 ---------- .../handlers/profile_handlers_core.go | 95 ++++
