Migrate: DokPloy, Komodo, Coolify, Dockge, Runtipi to Addons (#12275)

* feat: add Docker-based tool addons for dockge, komodo, dokploy, npmplus

Create addon scripts following the arcane.sh pattern for Docker-based
tools that can be installed on any existing Docker LXC:

- dockge: Docker Compose stack manager (port 5001)
- komodo: Build/deployment system with MongoDB/FerretDB (port 9120)
- dokploy: PaaS via external installer with Redis (port 3000)
- npmplus: Nginx Proxy Manager Plus via Compose (port 81)

Each addon includes:
- Docker availability check
- Install with full configuration
- Update via docker compose pull
- Uninstall with container cleanup
- ASCII header files

Original ct/ and install/ scripts are preserved for now.

* refactor: convert Docker tools to addons, remove old scripts

Convert dockge, komodo, dokploy, coolify from standalone ct/install
scripts to addon pattern (like arcane.sh).

Added:
- tools/addon/dockge.sh (port 5001)
- tools/addon/komodo.sh (port 9120, MongoDB/FerretDB choice)
- tools/addon/dokploy.sh (port 3000, external installer)
- tools/addon/coolify.sh (port 8000, external installer)
- tools/headers/ for all 4

Removed:
- ct/dockge.sh, ct/komodo.sh, ct/alpine-komodo.sh, ct/dokploy.sh, ct/coolify.sh
- install/dockge-install.sh, install/komodo-install.sh, install/alpine-komodo-install.sh
- install/dokploy-install.sh, install/coolify-install.sh
- frontend/public/json/ for dockge, komodo, dokploy, coolify
- tools/addon/npmplus.sh (not an addon candidate)

These tools are Docker-only and fit the addon pattern: they require
an existing Docker LXC and manage containers via docker compose.

* feat: add addon JSON configs for dockge, komodo, dokploy, coolify

Recreate JSON configs with type=addon, script paths pointing to
tools/addon/*.sh, null resources (addon runs on existing Docker LXC),
and update instructions in notes.

* feat: add Runtipi addon + upgrade all addons with Proxmox host check, optional Docker install, Alpine support

- New: tools/addon/runtipi.sh with full Alpine support (gcompat for musl)
- New: tools/headers/runtipi ASCII header
- Updated: runtipi.json to addon type with null resources
- Removed: ct/runtipi.sh, install/runtipi-install.sh (migrated to addon)
- All addons (dockge, komodo, dokploy, coolify, runtipi) now have:
  - check_proxmox_host(): warns when running on PVE host, default N
  - check_or_install_docker(): optional Docker install (Debian+Alpine)
  - Alpine-aware curl bootstrap and dependency installation

* readd ct, update information

* Create runtipi.sh

* refactor: remove inline header_info from addons, use core.func get_header()

- get_header() in core.func now maps APP_TYPE=addon to tools/headers/ path
- Removed 5 duplicate ASCII art header_info functions from addon scripts
- Addons now use the shared header_info() from core.func + tools/headers/ files

* chore(tools): add Github source links to dockge, komodo, dokploy, coolify, runtipi addons

* fix(runtipi): drop Alpine support; add OS compat notes to docker addon JSONs
