Introduce x-table toolbar/search/filter/sort/loading components and
multi-select deployment history filters with OR within groups and AND
across groups. Add live database/service status for breadcrumbs, shared
variables layout controls, logs viewer toolbar polish, and infrastructure
list filter consistency. Document patterns in UI_REDESIGN.md and cover
with feature tests.
Use `$this->mainServer` when resolving environment variable values across
deployment env generation (runtime, buildtime, nixpacks, args, and secrets
hash) so shared server-scoped values are applied consistently.
Also add `server_id` to `SharedEnvironmentVariable::$fillable` and normalize
the Livewire Blade file newline.
