docs: Add comprehensive samples catalog with structured metadata and deprecation warnings

[Copilot]

PR Type:

📚 Documentation content changes

What is the current behavior? 🤔

Sample and tutorial documentation lacks structured information. Users must click through to determine if a sample matches their requirements (project structure, .NET version, target platforms, dependencies). No warnings exist for deprecated packages (IdentityServer4 EOL Dec 2022, IdentityModel.OidcClient) or outdated migration guides (Silverlight). External tutorials presented without currency indicators.

What is the new behavior? 🚀

New Samples Catalog Page (samples-catalog.md, 260 lines)

Structured metadata tables for each sample:

| Property | Value |
|----------|-------|
| **.NET Version** | .NET 9.0+ |
| **Project Structure** | Single Project / Multi-head |
| **Target Frameworks** | iOS, Android, WebAssembly, Windows, macOS, Linux |
| **Key UnoFeatures** | Extensions, MVUX, Navigation, Http |
| **Third-party Packages** | With versions & warnings |
| **Tutorial Available** | Yes - Maintained in Uno Docs |
| **Status** | ✅ Active / ⚠️ Deprecated |

Navigation aids:

• Beginner starting points with recommended samples
• Filtering guidance by UnoFeatures and platforms
• Project structure explanations (Single Project vs Multi-head)

Safety warnings:

• IdentityServer4: ⚠️ EOL December 2022, migrate to Duende IdentityServer
• IdentityModel.OidcClient: ⚠️ Deprecated, use Uno.Extensions.Authentication.Oidc
• Multi-head projects: flagged as older pattern

Enhanced Community Tutorials Page

Transformed from simple list to structured resource:

#### Tutorial Title

**Author:** Name (Credentials)
**Link:** [URL]
**Published:** Date
**Type:** Multi-part series
**Topics:** Feature coverage
**Status:** ⚠️ External - verify currency

Added guidance on assessing tutorial currency (publication date, .NET version, project structure).

Silverlight Migration Warning

Added prominent CAUTION notice highlighting outdated content (2021 patterns, deprecated packages, legacy project structures) with links to current resources.

Sample Documentation Template (.sample-template.md)

Reusable template ensuring consistent metadata documentation for future contributions.

This section details on the original issue you should resolve

<issue_title>Improve sorting on samples, community tutorial and additional resources pages</issue_title>
<issue_description>### What could be improved? 🤔

The samples, tutorials and additional resources docs pages should contain a Table / information per Sample Entry, which will allow Consumers and especially Beginners, to see already before clicking on this Link, if those Specs are matching with the required or expected Information and are fluentless usable when starting from current Uno App templates.

Possibly bring the Issue Table from the Uno.Samples Repo to a Docs published Page or to their appropriate Entry in the Uno.Samples Sourced List of contained Samples:

• Update samples to latest Uno.Sdk 6.0 Uno.Samples#887

Important Information to include:

• Description of the sample (e.g. FoodDelivery has no Description

• The used Uno.Sdk and .NET Version

• Project Structure: Single Head (as provided by latest Uno Templates) or Multi Head

• List of TargetFrameworks which are proven to work for this Sample

• activly used and shown UnoFeatures in this sample

• used/required third Party Packages with version number.

  The Version Number would be important to know for example when the Package used is possibly depreciated, so the Consumer of this Sample App or Tutorial would be faced with an eventual additional Updating requirement, if the new version is even any longer compartible to Uno!
  Examples:

  • TimeEntryServices/IdentityServer Sample uses IdentityServer4 which is Depreciated as EOL up from December 2022!

  It is strongly advised to migrate to Duende IdentityServer.
  [...]

  • If you are on IdentityServer v4.x, you can immediately upgrade to Duende IdentityServer.

  • Authentication.OidcDemo uses the Depreciated IdentityModel.OidcClient AND is using Multi Head Project setup!

• Includes Step By Step Guide-Tutorial? Difference between:

  • Maintained in Uno Docs?

    • Contained in regular CommunityTutorials/Uno own Tutorials (like Counter etc) -> expectable to be up to date
    • OR Contained in Migration Docs? For example: Migrating from Silverlight is horribly out of date, but misses even a Agent Suitable Alert box to make them not consider those Information to be usable in current apps!!!

  • External Resource/Blog post? -> Potentially not up to date!

    • the "To Do" App, IS NOT the same as the Uno.Samples/Reference/ToDo + External ToDo App is still Multi Head Project, while the Uno owned version still misses completely a Tutorial
    • same like Uno.Samples/Reference/Commerce, which is only shown for Figma Plugin, but misses completely a Guide for those Users which might prefer our great new Hot Desingn or regular Hot Reload Development!

Key Changes:

• New samples catalog page with detailed metadata tables for each sample (Featured Applications, Workshop Projects, Uno.Samples Repository entries, and Legacy/Migration Samples)
• Enhanced community tutorials page with structured information including author credentials, publication dates, and currency assessment guidance
• Added prominent deprecation warnings to the Silverlight migration landing page highlighting outdated content from 2021
• New sample documentation template for future contributions
• Updated navigation structure separating "Samples Catalog" from "Samples Repository"
