Subject: [PATCH] fix: inspector stale data warning, remove dead
 supported_modes code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- inspector.html: show orange '⚠ Stale: HH:MM' with tooltip when link_stats data is >15 min old (previously just showed the time with no visual warning)
- style.css: add .g-stale-warn helper class (orange, bold) for the stale indicator
- diagnose.py: remove supported_modes accumulation from parse_ethtool() — field was collected but never consumed by analyze() or displayed anywhere
