[Feature+Fix] KeyCloak access to RM admin + bugfix +deps update

[benjamsf]

What Does This PR Do

• Add in KeyCloakUI access button to /app/admin/user-management. This is due as our version tag 1.6.0, we got Keycloak integrated.
• At footer, check & show users deployment version, rather than RMAPI version
• Fix few self-inflicted bugs with loginpage after the last merger
• Dependency upgrade

Keycloak button

Add Keycloak button behind an unfoldable card at ManageUsersView, pics below.

• This is really just useful for expert users at the moment
• And for them to tell that Here It Is instead of having to guess where it is

Version

Earlier the footer used the rmapi api/v1/healthcheck call and showed the version value there to users. This confused users a bit. So we now show them the deployment version according to whatever is the RELEASE_TAG (eg. 1.6.0) at present deployment.

• for this, we need to inject RELEASE_TAG env var to rmui's use at docker-compose.yml & for rmuidev at docker-compose-dev.yml.
• I'll be adding those in an integration repo pointer update PR once we're there

Bugfixes

These regard to the lastly merged QoL feature of automatically go to Callisign view, if we come with login code link (

• LoginView now awaits user manual input to the Formik form, instead of instantly polling whether a correct code was typed
• EnrollmentView does not flicker in some cases when an admin approves an user's enrollment, and the user is redirected to CreateMtlsView

Upgrades

• Upgrade deps
• Vite seems to require defining allowed hosts, so define them (per SERVER_DOMAIN var from env, and 0.0.0.0 from docker network)

Looks good! Clean and simple implementation.
