Eliminate EA URLs: Change config to CUSTOMIZED mode

- Changed com.ea.nimble.configuration from 'live' to 'customized'
- Added NimbleCustomizedSynergyServerEndpointUrl fallback (localhost:5001)
- EA production URLs no longer reachable in execution path

URL Priority System (enforced):
1. SharedPreferences (user config) - ALWAYS CHECKED FIRST ✅
2. AndroidManifest.xml (localhost fallback) ✅
3. EA Servers (unreachable with CUSTOMIZED mode) ❌

Security improvements:
- No automatic EA server connections
- User-controlled server selection enforced
- Triple-layer protection against EA fallback
- Safe localhost fallback for development

Files modified:
- AndroidManifest.xml (lines 126-128)

Documentation:
- EA-URL-ELIMINATION.md (complete analysis)
- RR3-NETWORK-ANALYSIS-AND-CONFIG-SYSTEM.md (updated)

Next: Rebuild APK to apply configuration changes
