[backend/frontend] XTM One registration and ping mechanism (#14798)

[SamuelHassine]

Proposed changes

• [backend/frontend] XTM One registration and ping mechanism

⚠️ This is a Proof of Concept (PoC) — validates the approach for XTM One registration before production hardening.

What this does

Implements a registration and periodic heartbeat between OpenCTI and XTM One:

• New xtmOneRegistrationManager — scheduled manager (every 5 min) that registers the platform with XTM One via /api/v1/platform/register. Fires once at boot (30s delay), then on interval. The endpoint is an upsert so repeated calls are safe.
• Registration payload includes platform metadata (URL, version, title, ID), enterprise license PEM/type, admin API key, and all platform users with dedicated XTM One API tokens (provisioned once per user, unlimited duration).
• Response handling — stores the chat_web_token from XTM One for Copilot chat integration.
• New config key xtm.xtm_one_token — both xtm_one_url and xtm_one_token must be set for the manager to activate.
• Improved auth logging — token resolution errors now include token prefix, user-agent, and origin.
• i18n — new manager label across all supported languages.
