Dashboard configuration page should document `aspire dashboard run`

[afscrome]

Aspire 13.3 introduced the preview aspire dashboard run.

https://aspire.dev/dashboard/configuration/#standalone-dashboard should include how to set max log levels via aspire dashboard run

I think the configuration would be applied as folows:

aspire dashboard run \
    --Dashboard:TelemetryLimits:MaxLogCount 1000 \
    --Dashboard:TelemetryLimits:MaxTraceCount 1000 \
    --Dashboard:TelemetryLimits:MaxMetricsCount 1000

https://aspire.dev/dashboard/security-considerations/ is another page that should prefer aspire dashboard run over docker run -it commands

Pages

• src/frontend/src/content/docs/dashboard/configuration.mdx (the Standalone dashboard section)
• src/frontend/src/content/docs/dashboard/security-considerations.mdx (also currently uses docker run -it …; prefer aspire dashboard run)

Scope: Aspire 13.3 introduced the preview aspire dashboard run command. Add coverage that mirrors the existing docker run … examples (and where appropriate, replaces them) — including how to set telemetry limits and other configuration via CLI args, e.g.:

aspire dashboard run \
    --Dashboard:TelemetryLimits:MaxLogCount 1000 \
    --Dashboard:TelemetryLimits:MaxTraceCount 1000

Acceptance

• Standalone dashboard config section shows aspire dashboard run as the primary path, with the docker run form retained as the container-only fallback.
• Security-considerations page uses aspire dashboard run examples where it currently shows docker run -it.
• Confirm flag syntax against microsoft/aspire 13.3 sources before committing.
