fix(cli): reload config on each daemon sync cycle

[Phil-Fan]

Summary

• Reload config from disk before every daemon sync iteration so changes made via tokenarena config set (apiKey, apiUrl, etc.) take effect without a manual service restart

Context

The daemon only called loadConfig() once at startup, then reused that config object in its sync loop. After modifying config values, the daemon continued using stale credentials, causing "Could not fetch usage settings" errors until tokenarena service restart was run.

Test plan

• Start daemon with valid config
• Run tokenarena config set apiKey <new-key>
• Verify daemon picks up the new key on the next sync cycle (no restart needed)
