fix: improve dashboard and lifecycle

[OwendB1]

• Persist dashboard card/list mode and add card-view Create Server, config-profile, and direct-connect port actions.
• Copy direct-connect host:port from dashboard cards and the server list, using configured server IP with browser-host fallback for wildcard binds.
• Suppress simulation-baseline collection as a warning while keeping the state visible on server cards.
• Make Quasar.Agent own !stop, !restart, and !quit. !restart sends AdminRestart so Quasar keeps goal On and relaunches; !quit exits without saving while setting goal Off.
• Log Quasar and Magnetar/Quasar.Agent versions on startup.
• Show installed Magnetar and Dedicated Server versions/paths on Updates, with separate manual Magnetar and DS check buttons.
• Refresh architecture, state-machine, deployment, and generated reference docs.

Verified:

• dotnet build Quasar.sln -v minimal
• git diff --check
