* fix(snap): simplify snap hooks
The `post-refresh` hook runs after initial snap installation as well, so
there is no need to call the `install` hook from within the
`post-refresh` hook; instead, the logic can simply be moved into the
`post-refresh` hook directly, and the `install` hook removed.
Also, the existing `install` hook logic looked for an insecure
configuration, and if found, replaced the entire configuration file with
a minimal default in the current format. But OpenShell does that default
behavior without any config file, so we may as well simply remove the
configuration file entirely to keep up-to-date with the current default
behavior. Let OpenShell create a configuration file if it needs to,
rather than auto-create one via the packaging scripts.

* fix(snap): remove the connect-plug-docker hook
The `openshell:docker` is auto-connected to the system `:docker` slot,
so there should not be a need to separately restart the gateway service
when the interface is connected.
For locally-built test snaps which were not published to the store, the
autoconnection is not made, but when the snap is installed, the gateway
will attempt to start anyway and fail to find any available compute
driver, so quickly restart until it hits the systemd start-limit, after
which systemd prevents the service from being started again. If a user
tries to manually connect their locally-built `openshell` snap to the
`:docker` slot, then the `connect-plug-docker` hook runs and triggers a
restart of the gateway, which will usually fail because the start limit
has already been hit. An error in the hook will thus cause the interface
connection to be undone, which is undesirable.
Thus, we can remove this hook entirely, and instead allow interface
connections to succeed as intended. The user still needs to manually
restart the gateway service after making a manual connection (as was the
case previously) and probably needs to `systemctl reset-failed` first,
but at least connection will succeed beforehand so they can proceed with
these steps.

* fix(snap): set refresh-mode: endure again, with manual restart
Return to the previous behavior before commit a67567e58, where the
gateway is not stopped before refreshes. The `post-refresh` hook
now restarts the gateway if the TLS configuration was corrected, so we
don't have to enforce restarting the gateway on every refresh even when
not necessary. Thus, set `refresh-mode: endure`, and let the hook decide
when the gateway needs to be restarted.
