refactor(web): migrate to SWR for data fetching

[silent-cipher]

closes #474

[Copilot]

Pull request overview

This PR migrates the web app’s config/providers data fetching to SWR to ensure requests like /api/config are deduplicated and cached across multiple consumers (addressing duplicate fetches noted in #474).

Changes:

• Add SWR and configure global SWR defaults in the web app entrypoint.
• Refactor useNetworkConfig and useProvidersList to use SWR with shared fetcher + cache keys (apiPaths).
• Update web tests to mock SWR-backed hooks and isolate SWR cache per test where needed.

@silent-cipher : I wanted to check: is there any issues with merging in this work before GA? I want to make sure we don't impact GA with adding multiple-network support to dealbot. We absolutely should get that added to dealbot, but I'd preferr to live with the status quo to keep us stable at the moment.

[silent-cipher]

No, I don't see any issues with merging this before GA. Agreed that stability is what we should optimize for right now.
