Fixes #211

Before: clicking the bookmarklet opened Quick Add and the post showed up twice in the library.

After: the bookmarklet saves exactly one post. Opening Quick Add again for a URL that is already saved shows the existing post instead of adding another copy.

The page is prerendered and then rendered again once the interactive circuit connects, and each pass called the extract-and-save API, which creates a new row every time.

How

• QuickAdd.razor checks RendererInfo.IsInteractive and, while prerendering, only shows the progress spinner; the save runs once, in the interactive render. The MAUI app's BlazorWebView is always interactive, so it is unaffected.
• POST /api/posts/extractPostDetails now looks up the URL first (new DataStorageService.GetPostByUrl) and returns the stored post if there is one. This also protects the Posts page and suggestion list, which call the same API. Re-adding an already read post returns that post rather than creating a fresh unread one.

Tests

• QuickAddTests: new test renders the page in prerender mode and then interactive mode and asserts a single save; another asserts the prerender pass shows the spinner and does not save. Both fail on v-next and pass here. Existing tests now set an interactive renderer.
• PostEndpointsTests: calling extract twice for the same URL returns the same post and stores one row (fails on v-next, passes here).
• DataStorageServiceTests: GetPostByUrl found / not found.
• Run locally: BlazorApp tests 63/63. API tests were run against a local Azurite (no Docker in the sandbox); the only failures were ExtractPostDetails_WithValidUrl_ReturnsOkWithPost, which needs to fetch docs.microsoft.com, and a cross-test data leak caused by sharing one emulator across test classes. CI uses per-class containers.

Existing posts already saved twice are not cleaned up (out of scope per the issue).
