feat: default browserless onboarding and request strategies

[gildesmarais]

Summary

• default the onboarding flow to the JavaScript/browserless strategy and keep the utility links aligned with that path
• expose featured included feeds at the API root and allow embedded config lookup for built-in feed paths
• align generated feed defaults and onboarding tests with the current request-service strategy baseline

Verification

• docker compose -f .devcontainer/docker-compose.yml run --rm app make setup
• docker compose -f .devcontainer/docker-compose.yml run --rm app make ready
• browser smoke in chrome-devtools at http://127.0.0.1:4001/ covering guest, token-required, and success states

Pull request overview

Updates the html2rss-web onboarding and metadata surfaces so new users default to the browserless/JavaScript strategy, while also promoting built-in/embedded feed configs via the API and UI.

Changes:

• Defaults onboarding strategy selection to browserless in the frontend (with auto-submit support for ?url= flows) and aligns tests/mocks.
• Exposes featured_feeds on the API v1 root metadata and adds backend support for resolving embedded config paths via LocalConfig.
• Updates backend defaults to defer to Html2rss::RequestService.default_strategy_name instead of hard-coding :faraday.

@gildesmarais you don't need @hey-api/client-fetch in dependencies anymore, it's been deprecated and is unused
