[PR] [ISSUE-3788][test] Deepen ProxyConsumerResolverTest with blank-instance cache share, address filtering and running-info fallback [rocketmq-dashboard]

["yyqdbngt (via GitHub)" <gi...@apache.org>]

yyqdbngt opened a new pull request, #3788:
URL: https://github.com/apache/rocketmq-dashboard/pull/3788

   ### Motivation
   
   The existing `ProxyConsumerResolverTest` covers discovery derivation, caching, transient retry and the connection-query null degradation, but three guard paths were unverified: the shared cache key for blank instance ids, the filtering of blank client addresses during discovery, and the running-info fallback when no proxy is discovered.
   
   ### Changes
   
   - `discoverProxyAddressesShouldShareCacheForBlankInstanceKeys`: null and whitespace-only instance ids map to the same default cache key, so the second lookup is served from cache.
   - `discoverProxyAddressesShouldSkipBlankClientAddresses`: entries with null or whitespace-only client addresses are filtered out, leaving only valid proxy remoting addresses.
   - `resolveConsumerRunningInfoShouldReturnNullWhenNoProxyDiscovered`: a discovery failure degrades the running-info query to null so the caller can fall back to the broker path.
   
   ### Verification
   
   ```
   mvn -B test -Dtest=ProxyConsumerResolverTest
   [INFO] Tests run: 8, Failures: 0, Errors: 0, Skipped: 0
   [INFO] BUILD SUCCESS
   ```
