Centralize effective-provider resolution.

This branch correctly maps a first-party MiniMax endpoint to the minimax model configuration. However, the conversion is local. getAPIProvider() still returns firstParty, so src/utils/model/deprecation.ts never selects the new minimax: null retirement entries, and the minimax provider label in src/utils/status.tsx is unreachable.

Extract a shared effective-provider helper and use it for model, deprecation, and provider metadata lookup. Keep the raw provider where the first-party transport and base-URL branch are required. Add tests covering both MiniMax hosts.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Reject malformed configured URLs.

getAnthropicBaseUrlHost() returns null when ANTHROPIC_BASE_URL is unset and when new URL(baseUrl) fails. isFirstPartyAnthropicBaseUrl() then returns true for both cases. A value such as ANTHROPIC_BASE_URL=not-a-url is accepted instead of rejected.

Treat only an unset value as the default API. Return false for a configured value that cannot be parsed. Add tests for unset, malformed, allowed, and disallowed URLs.

Proposed fix 
 export function isFirstPartyAnthropicBaseUrl(): boolean {
+  if (!process.env.ANTHROPIC_BASE_URL) {
+    return true
+  }
   const host = getAnthropicBaseUrlHost()
   if (!host) {
-    return true
+    return false
   }
