[ECO Bounty] ioTexScan No Record for 5D Time Range on Staking Ratio History Chart

Page URL: https://iotexscan.io/charts/staking-ratio

Issue Summary:
The "Staking Ratio History" chart shows no data ("No Record") specifically for the "5D" (5 Days) time range, resulting in an empty graph. Longer ranges (e.g., 1M, YTD) may partially load, but short-term recent data is missing. Top metrics like IOTX Price and Gas display as "- No Data". Confirmed live on the page—no recent staking ratio data populates.

Screenshot Details (from your image):

• Mobile view (Android, 3:59 AM).

• Orange arrow points to empty chart under "5D" selection in "Staking Ratio History".

• Time selectors: 5D 1M 6M YTD 1Y ALL (5D active but blank).

• X-axis vague (~2026 dates?), but no recent bars/data visible.

• Section: CHARTS & STATS > STAKING RATIO.

Steps to Reproduce:

1. Open https://iotexscan.io/charts/staking-ratio in any browser (mobile/desktop).

2. Click "5D" under "StakingRatioHistory".

3. Result: Empty chart with no data for last 5 days. Metrics remain blank ("IOTX Price: - Gas: -"). Switching ranges doesn't fully resolve.

Expected Behavior:

• "5D" view should show staking ratio trends for the past 5 days, up to current date (Feb 27, 2026).

• All time ranges should load dynamically with live IoTeX network data.

• Metrics (IOTX Price, Gas) should display real-time values.
