…ban steps, feeds version - Health ERRORS section now shows issues from checks with ERROR status even if they didn't add explicit NFTBAN_HEALTH_ERRORS entries (e.g., GUI auth socket) - Services in status show INACTIVE (optional) instead of bare INACTIVE - Services report disables ANSI colors when stdout is not a terminal (no garbage in logs/pipes/tickets) - Ban output shows Step 4 (persistent offender check) with result messages - Feeds header uses actual NFTBAN_VERSION instead of hardcoded v1.0.0 Addresses UX report issues #3, #4, #6, #7, #8.
