fix: crowdsec web console enrollment

[Wikid82]

Problem Statement

Issue: #586 - CrowdSec engine showing as offline in console since 12/19/25

CrowdSec console enrollment has been experiencing reliability issues where the engine appears offline in the crowdsec.net web console despite being enrolled locally. Users cannot determine if their CrowdSec instance is properly enrolled and actively reporting to the console, leading to uncertainty about security posture.

Root Causes Identified

1. Silent Enrollment Failures - No validation for token expiry before enrollment
2. LAPI Initialization Timing - Only 3 retries with 6s total wait (insufficient for slow hardware)
3. Missing Heartbeat Tracking - LastHeartbeatAt field exists but never updated
4. Network Connectivity Issues - No diagnostic tools to verify crowdsec.net reachability
5. Inadequate Test Coverage - No E2E tests for console enrollment flow

---

Solution Approach

This PR implements a comprehensive debugging and testing strategy following the specification in docs/plans/crowdsec_enrollment_debug_spec.md.

Architecture Components

• Console Enrollment Service (backend/internal/crowdsec/console_enroll.go) - Handles enrollment with retry logic
• Heartbeat Polling Service (NEW) - Tracks console connectivity and updates status automatically
• Diagnostic Endpoints (NEW) - Comprehensive health checks for troubleshooting
• Enhanced Validation - Token validation, LAPI readiness checks, network connectivity tests

---

Implementation Phases

Phase 1: Diagnostic Tools ✅

• ✅ Console connectivity check endpoint
• ✅ Config validation endpoint
• ✅ Heartbeat status endpoint (placeholder)
• ✅ Comprehensive diagnostic script

Deliverables:

• GET /api/v1/admin/crowdsec/diagnostics/connectivity - Verify crowdsec.net reachability
• GET /api/v1/admin/crowdsec/diagnostics/config - Validate CrowdSec configuration files
• scripts/diagnose-crowdsec.sh - Automated diagnostic tool

Phase 2: Enhanced Validation 🚧

• 🚧 Increase LAPI check retries (3→5 with exponential backoff)
• 🚧 Token expiry detection
• 🚧 Improved error messages with specific remediation guidance
• 🚧 CAPI registration validation

Deliverables:

• Enhanced retry logic: 3s, 6s, 12s, 24s delays
• Context-aware error messages with actionable instructions
• Pre-enrollment validation for tokens

Phase 3: Heartbeat Monitoring 📋

• 📋 Heartbeat polling service implementation
• 📋 Automatic status transitions (pending_acceptance → enrolled)
• 📋 LastHeartbeatAt field population
• 📋 Prometheus metrics for enrollment success/failure rates

Deliverables:

• backend/internal/crowdsec/heartbeat_poller.go - Background service polling console every 60s
• Metrics: charon_crowdsec_enrollment_attempts_total, charon_crowdsec_lapi_healthy
• Auto-detection of user-accepted enrollments

Phase 4: Comprehensive Testing 📋

• 📋 Unit tests for enrollment service (token validation, LAPI checks, CAPI registration)
• 📋 Integration tests for LAPI connectivity (startup, health, persistence)
• 📋 E2E tests for console enrollment flow (happy path, validation errors, status display)
• 📋 E2E tests for diagnostic endpoints

Test Coverage Targets:

• Unit tests: 100% coverage for new enrollment logic
• Integration tests: LAPI startup, CAPI connectivity, config persistence
• E2E tests: enrollment flow, error handling, diagnostics

The use of a map for errorPatterns combined with a range loop makes the selection of messages nondeterministic when multiple patterns match the same output, because Go does not guarantee map iteration order; if you ever have overlapping patterns (e.g., a string containing both "token is invalid" and "no such file or directory"), which user-facing message is returned will vary between runs. To make the behavior predictable and easier to reason about, consider changing this to a slice of pattern/message pairs and iterating in a fixed priority order.
