* feat: make the server config file mode configurable
/etc/rancher/k3s/config.yaml holds the cluster token. The server and
upgrade roles write it at 0644, so every local account on a server node
can read the credential that joins a node to the cluster.
k3s_server_config_mode sets the mode of that file in both roles. It
defaults to 0644, so behaviour is unchanged unless it is set.

* docs: describe the server config file contents accurately
/etc/rancher/k3s/config.yaml does not always carry the cluster token. A
first server that lets K3s generate one writes the file without it, so the
file can contain the token rather than always holding it. Correct that
claim in the README, the inventory sample and the role default, and use
the US spelling of "honors".

* Name the floor the config file mode can be narrowed to
Saying any mode root can read works leaves the reader to work out what
that means in practice. The file is read only by k3s, running as root, so
0600 is the tightest mode that still works.

* Run the basic integration job with a non-default config file mode
The templated mode was only ever rendered with its default in CI, which
is the one value that cannot tell a working template from a broken one.
The basic inventory sets 0640 and the job reads the mode back off the
installed file.

* feat(k3s_upgrade): regenerate service files from templates instead of restoring backups
The k3s_upgrade role previously restored backup service files after binary
upgrade, which meant any changes to extra_server_args or extra_agent_args
would not be applied during upgrades.
This change:
- Replaces backup restoration with template-based service file regeneration
- Reuses templates from k3s_server role via symlink
- Adds necessary defaults for template variables
