Refactor proxyFetch and enhance MediaProviderDetailPage layout

- Removed the isCloud check from proxyFetch.js, simplifying the fetch patching logic.
- Updated MediaProviderDetailPage to include a new section for API key retrieval, improving user experience with clearer layout and additional notice text.
- Enhanced ConnectionRow to better handle email display names.
- Improved ProviderDetailPage to conditionally render provider notices and API key links.
- Refactored localDb, requestDetailsDb, and usageDb to remove unnecessary isCloud checks, streamlining database interactions.
- Updated OAuthModal to combine waiting and manual input steps for a more cohesive user flow.
- Added API key URLs to several providers in providers.js for better accessibility.
