[feature] Randomize rating links

[paul-fresquet]

Summary

• Move rating prompt labels into configuration with per-locale text and clean fallbacks
• Load rating prompt configuration from embedded settings with validation/normalization
• Keep existing rating prompt behavior (Store + always-include + random additional)

Changes

• Add config model + provider for rating prompts (probability, counts, channels, per-locale labels)
• Update rating prompt service to resolve labels via culture fallback and domain fallback
• Expand tests to cover config parsing, label resolution, and selection behavior
• Remove obsolete rating-channel entries from resx/designer
• Update rating prompt schema in local settings template

Implementation

• Parse RatingPrompt section into typed configuration with graceful defaults
• Resolve labels by exact culture, neutral culture, then �n, then URL domain
• Keep deterministic selection with injected random provider for tests

Pull request overview

This PR refactors the rating prompt system to move channel labels from hardcoded resource files into a flexible configuration system. The changes introduce a configuration provider that loads rating prompt settings from JSON, supporting per-locale labels with culture fallback logic (exact culture → neutral culture → English → domain name). The PR maintains existing behavior where Store channels are shown for MSIX installations, while non-MSIX installations show AlwaysInclude channels plus randomized Additional channels.

Key changes:

• Introduced RatingPromptConfiguration and RatingPromptConfigurationProvider to parse and validate rating prompt settings from configuration
• Updated RatingPromptService to use configuration-driven labels with culture fallback chain
• Added comprehensive test coverage for configuration parsing and label resolution
• Removed obsolete rating channel entries from resource files
