When creating a node on a remote compute, the controller now sends
only the image filename instead of the absolute local path. The remote
compute will search for the image in its own configured images_directories.
If the image is not found, the compute returns ImageMissingError, which
triggers the controller's automatic image upload mechanism.
This fixes issue #2676 where remote computes reject paths from the
controller due to mismatched directory prefixes.

Fixes#1658
Add validation in the update_template method to check if a template
with the same name already exists before updating. This prevents
users from creating duplicate template names by editing existing
templates.
The check excludes the current template being edited to allow
updating other properties without changing the name.
When updating a compute without providing a password field,
compute_update.password is None and calling .get_secret_value()
on it causes a 500 Internal Server Error. Only set the password
in update_values when a password is actually provided.

When a hostname validation fails, the error message now includes
the allowed character set to help users provide valid names.

Add documentation explaining the common issue where WebSocket console connections to remote compute nodes fail due to credential mismatch. The guide describes the error symptoms, root cause (Controller forwarding its own credentials to Compute), and solution (ensuring matching compute_username and compute_password in Compute's configuration).
This section was misleading - the actual root cause is host=0.0.0.0
causing controller to register as 127.0.0.1, not hostname resolution.

Add details about the "No common subnet" error when Controller's host
is set to 0.0.0.0, and how to verify via /v3/version endpoint.

Add documentation for the "No common subnet" error when the
controller's hostname in /etc/hosts resolves to an unreachable
or stale IP address.

The CLI entry point was renamed from 'wireshark' to 'gns3server-web-wireshark-setup'
to avoid conflicts with the system wireshark package.

The wireshark CLI entry point creates /usr/bin/wireshark which conflicts
with the system wireshark package on Arch Linux (owned by wireshark-qt),
causing package installation to fail.
Rename to gns3-wireshark to follow the same naming convention as other
GNS3 CLI tools (gns3server, gns3vmnet).

Add verify=False to requests.get() when capture_url uses HTTPS protocol,
to skip SSL certificate validation. This allows PacketCaptureTool to
work with GNS3 servers using self-signed certificates.

Add -k flag to curl command when capture_stream_url uses HTTPS protocol,
to skip SSL certificate validation. This allows Web Wireshark to work
with GNS3 servers using self-signed certificates.

- Document API version negotiation mechanism (1.44 with fallback to 1.40)
- Add tested configurations table for Docker 20.10 and 29.3+
- Document container IP retrieval dual-strategy approach
- Explain KeyError bug fix for missing NetworkSettings.Networks field

- Change initial API version from 1.40 to 1.44 to support Docker 29.3+ (API 1.54)
- Add automatic fallback to API 1.40 for older Docker versions (20.10, API 1.41)
- Fixes "client version 1.40 is too old. Minimum supported API version is 1.44" error
- Ensures compatibility across Docker versions 20.10 (API 1.41) to 29.3+ (API 1.54+)

- Add `get_container_ip` method to WebWiresharkManager for retrieving container IP addresses in wireshark network
- Method uses Docker API as primary approach with container command execution as fallback
- Refactor web_wireshark_websocket endpoint to use new method instead of direct Docker queries
- Improve error handling and logging for container IP retrieval failures
The minimum Docker API version was reduced from 1.44 to 1.40 to support older Docker installations that do not provide API version 1.44, ensuring the web Wireshark agent can connect to a wider range of Docker environments.

when syncing WebUI with gns3server.
