rcourtman a4d37447a0 Give the Docker-in-LXC opt-in an admin Settings toggle
Discovering Docker inside Proxmox LXC guests previously required an
undocumented environment variable plus a hand-edited systemd unit,
which is how the surface kept shipping invisible. The opt-in is now a
persisted system setting with an admin-only toggle in Settings →
System → General, presented as its own "Docker in Proxmox LXCs" card
under the existing Docker/Podman updates card, with the requirements
(node agent with command execution) and data-collection bounds stated
inline.

The setting rides the admin-gated system settings endpoint
(RequireAdmin + settings:write, matching every other server-wide
toggle). Flipping it persists first, then applies to the runtime
config and fires a reconfigure hook so the router rebuilds the
monitor's Docker checker and inventory collector immediately — no
restart. PULSE_ENABLE_PROXMOX_GUEST_DOCKER_INVENTORY remains
authoritative: when set it locks the toggle (EnvironmentLockBadge in
the UI, HTTP 400 from the API), and an unrelated settings save can
never clobber the runtime value. The opt-in guardrail test now pins
the settings path, the env lock, and the persisted field.

Installer and node setup-guide callouts now point at the toggle first
with the environment variable as the locking override, and the docs,
their public mirrors, and the agent-lifecycle subsystem contract say
the same. New i18n strings shipped for en/de/es.

Verified live in mock mode: toggle off/on from the UI drives the
collector teardown/setup log lines, the value survives a server
restart, and all three touched surfaces render at desktop and mobile
widths (receipt in frontend-modern/browser-verification.json).

Internal API Package

This directory contains the API server implementation for Pulse.

Important Note About frontend-modern/

The frontend-modern/ subdirectory that appears here is:

  • AUTO-GENERATED during builds
  • NOT the source code - just a build artifact
  • IN .gitignore - never committed
  • REQUIRED BY GO - The embed directive needs it here

Frontend Development Location

👉 Edit frontend files at: ${PULSE_REPOS_DIR}/pulse/frontend-modern/src/

Why This Structure?

Go's //go:embed directive has limitations:

  1. Cannot use ../ paths to access parent directories
  2. Cannot follow symbolic links
  3. Must embed files within the Go module

This is a known Go limitation and our structure works around it.
