feat(onboarding): route plugin installs through ca.unraid.net/dl proxy

[Squidly271]

Summary

• Prefix the three recommended plugin URLs in the onboarding flow with https://ca.unraid.net/dl/ so installs go through the Community Applications download proxy instead of hitting raw.githubusercontent.com directly.
• Updates the URL list in OnboardingPluginsStep.vue and the parallel pluginMap in OnboardingSummaryStep.vue (the latter is what's actually passed to the installPlugin mutation).
• Updates the matching test expectation in OnboardingSummaryStep.test.ts.

Why

Routing through ca.unraid.net/dl/ lets the install traffic go through the same download proxy CA uses, rather than each user pulling the .plg straight from GitHub.

Notes for reviewers

• The trailing .plg filename is preserved at the end of every URL, so the existing installed-plugin detection logic (which compares basenames against the contents of /boot/config/plugins) is unaffected. Tailscale's tailscale-preview.plg alias still works.
• The backend's validateInstallUrl (api/src/unraid-api/graph/resolvers/unraid-plugins/unraid-plugins.service.ts) only requires an http/https URL whose pathname ends in .plg, so the prefixed form passes validation.
• I was unable to run the web vitest suite locally — pnpm install fails on macOS for an unrelated native module (@unraid/libvirt node-gyp build). The change itself is mechanical (string-only edits with a matching test update). Would appreciate a CI run to confirm.

Test plan

• CI passes (pnpm test, pnpm lint, pnpm type-check)
• Manually walk through onboarding and confirm each recommended plugin (Community Apps, Fix Common Problems, Tailscale) installs successfully via the proxied URL
• Confirm "already installed" detection still works when one of the plugins is present in /boot/config/plugins

Walkthrough

The PR updates plugin download URLs across the Unraid onboarding flow to route through a proxy service (ca.unraid.net/dl/). Three plugins—community-apps, fix-common-problems, and tailscale—have their download URLs modified in both the plugin step and summary step components, with a corresponding test expectation update.

Changes

Plugin URL Proxy Routing

Layer / File(s)	Summary
Plugin URL Configuration web/src/components/Onboarding/steps/OnboardingPluginsStep.vue, web/src/components/Onboarding/steps/OnboardingSummaryStep.vue	Plugin URLs for community-apps, fix-common-problems, and tailscale are wrapped with https://ca.unraid.net/dl/ proxy prefix instead of using direct GitHub or Unraid source URLs.
Test Expectations web/__test__/components/Onboarding/OnboardingSummaryStep.test.ts	Test assertion for plugin installation URL is updated to expect the ca.unraid.net/dl/ wrapped URL format.
