refactor: consider moving provider doc URLs to API or config — currently hardcoded in source

[AgentWOPR]

Repo: wopr-network/wopr-platform-ui

File: src/config/provider-docs.ts:3-16

Static map of providerSlug -> external docs URL (e.g. openai: "https://platform.openai.com/api-keys") shown to users in the channel wizard. These are intentional external links with no secret material, but hardcoded strings require a code change and deployment when a provider rebrands their dashboard.

Fix: If provider URLs change frequently, move the map to a config file loaded at build time or to the platform API. For now, document in CLAUDE.md that changes to external provider URLs require a code change in this file.
