CF7 to API v2.1.0

Added

• Granular Alert Preferences: Per-submission failure alerts with granular control

  • New alert_types setting structure with threshold and individual options
  • maybe_send_individual_alert() triggers when a submission permanently fails after all retries
  • Individual alerts are event-driven (no cooldown) vs rate-limited threshold alerts
  • Privacy-first design: alert emails contain only error metadata (form name, endpoint, timestamp, response code, error message) - never user-submitted form data
  • Spam prevention: transient flag per log_id prevents duplicate alerts on retry
  • UI: "Alert Types" section with nested checkboxes for threshold and individual alerts
  • Threshold settings reorganized under clear subheading
  • Backward compatible: threshold alerts enabled by default, individual disabled
  • Integrated in LogsController::handle_retry_action() for retry exhaustion and max limit scenarios

• Response Action Hook (cf7_api_after_response): New filter hook for extending plugin functionality

  • Fires after each API response is received (success or failure)
  • Provides complete response data (status code, headers, body, parsed JSON, duration)
  • Includes submission context (log ID, form ID, form title, form data, endpoint, retry info)
  • Enables developers to:
    • Store CRM lead IDs returned by APIs
    • Trigger notifications based on response content
    • Log to external monitoring services (Sentry, Bugsnag, etc.)
    • Send data to secondary endpoints (multi-endpoint support)
  • Hook only fires for HTTP responses (not WP_Error cases)
  • Minimal overhead when no callbacks are registered
  • See docs/API_REFERENCE.md for complete documentation and examples

• Form Filter Dropdown: Visible dropdown selector to filter logs by Contact Form 7 form

  • Dropdown appears in filter controls between Status and Date filters
  • Lists all forms that have at least one log entry
  • Shows "All Forms" default option to display logs from all forms
  • Gracefully handles deleted forms (displays as "Form #123")
  • Auto-submits on selection for immediate filtering (no button click needed)
  • Active filter tag shows selected form with individual remove capability
  • Filter persists across pagination and combines with status/date filters
  • Alphabetically ordered by form title for easy navigation
  • New LogReader::get_forms_with_logs() method retrieves distinct forms with logs
  • Comprehensive unit test coverage (6 tests for all scenarios)
