Remove all SPICE WebSocket-related code due to frontend dependency issues
with spice-html5 library (missing RSAKey/BigInteger implementations).
Changes:
- Remove start_spice_websocket_console() from BaseNode
- Remove SPICE WebSocket endpoints from QEMU and Docker compute APIs
- Remove SPICE WebSocket proxy endpoint from controller API
- Remove WebSocket subprotocol handling from authentication layers
- Remove SPICE documentation
The SPICE console type remains functional for direct connections,
but WebSocket proxy support has been removed.

Add WebSocket-based console support for SPICE protocol, enabling
browser-based graphical console access with enhanced features
like clipboard sharing, USB redirection, and audio streaming.
Changes:
- Add start_spice_websocket_console() method in BaseNode for SPICE
WebSocket to TCP bridging with bidirectional binary forwarding
- Add /console/spice WebSocket endpoints in QEMU and Docker compute APIs
- Add /console/spice WebSocket proxy endpoint in controller API
- Add comprehensive API documentation in docs/features/
Supported console types:
- spice: Basic SPICE protocol support
- spice+agent: SPICE with spice-vdagent for enhanced features
Architecture:
- Browser WebSocket → Controller (JWT + RBAC) → Compute (Basic Auth)
- No external websockify processes required
- Consistent with existing VNC WebSocket implementation
Add VNC console WebSocket endpoints for Docker and QEMU nodes:
- Add /console/vnc WebSocket endpoint to compute API (Docker & QEMU)
- Add /console/vnc WebSocket endpoint to controller API
- Implement start_vnc_websocket_console() in BaseNode
- Forward VNC WebSocket traffic between controller and compute layers
The implementation provides bidirectional WebSocket to TCP forwarding
for VNC protocol (RFB) connections, allowing browser-based VNC console
access to containers and VMs.

When a Docker container with the same name already exists (e.g., from a
previous crashed GNS3 session), Docker returns a 409 Conflict error
when trying to create a new container with that name. This causes the
project open operation to fail.
This fix adds automatic cleanup of stale containers when encountering
a name conflict:
- Added DockerHttp409Error exception class
- Updated http_query to detect 409 status codes
- Modified create() to remove conflicting containers and retry
Fixes the issue where opening a project fails with:
"Docker has returned an error: 409 Conflict. The container name
'/GNS3.xxx' is already in use by container 'xxx'"
Add an additional fallback check for the VBoxManage executable using the capitalized "VBoxManage" command name. This improves compatibility on systems where the executable may be case-sensitive or installed with a different naming convention, ensuring the VirtualBox manager can locate the necessary binary when the lowercase "vboxmanage" is not found.
asyncio.get_running_loop() raises RuntimeError when emit() is called
from a thread without an active event loop (e.g. when the disk space
check in project_manager triggers a log.warning notification from a
threadpool worker).
This causes a 500 Internal Server Error on project creation/open when
disk usage is high, instead of the intended warning notification.
Wrap the emit loop in try/except RuntimeError so that notifications
are silently dropped when no event loop is available, rather than
crashing the request.

On musl-based systems (Alpine), ldd returns exit code 0 for static
binaries, unlike glibc which returns 1. This causes install_busybox()
to reject all busybox binaries as "dynamically linked" on Alpine.
Fix by also accepting binaries whose executable name contains "static"
(i.e. busybox-static, busybox.static), which are the first two
candidates checked by the function. The generic "busybox" fallback
still relies on the ldd return code check.
Most VNC clients use the Desktop name in their window title.
Currently this defaults to user@host which means all docker vnc
connections have identical window names of e.g.
SSVNC: gns3@gns3server
This uses the node name instead.
* Offset pci_device_id for network devices by 32 (formerly 4)
to reserve first 32 IDs for non-netdev devices
* This implies a new pci_bridge for the netdevs and
the pci_device_ids starting at 0 (using modulo)
* Fixes a bug in the creation of the qemu command
when the number of qemu pcie devices (storage_controller, disks, …)
was greater than 4 and the number of network devices
saturated the 32 pcie ids of the root bridge
causing qemu not to start.
