[ECO Bounty] iopay qr code need space

Description: The News section's category filter is displaying an internal system tag labeled #Import 2026-01-27 01:16 as a selectable filter option. This appears to be an internal tracking tag (likely used for content management/import operations) that is being incorrectly exposed to end users in the frontend interface.

Steps to Reproduce:

1. Navigate to https://hub.iotex.io/explore#news

2. Observe the filter/checkbox list below the search bar

3. Look for the second item in the filter list

Expected Result: Filter options should only display user-facing content categories such as "News," "Community," "Governance," "Developers," and "DePIN."

Actual Result: A filter option labeled #Import 2026-01-27 01:16 (30) appears in the list, suggesting 30 items are tagged with this internal import marker. This tag is not meaningful to end users and clutters the UI.

Environment:

• Platform: Mobile (Android)

• Browser: Chrome Mobile

• Screen resolution: Mobile viewport

• Date observed: February 6, 2026

Additional Context:

• The tag includes a specific timestamp (2026-01-27 01:16), suggesting it was auto-generated during a bulk content import operation

• The tag shows 30 items associated with it, indicating a significant portion of the news content may have been imported during this batch

Suggested Fix: Filter out internal/system tags (those prefixed with #Import or similar internal markers) from the public-facing category filter UI, or properly categorize imported content under user-facing taxonomy terms before publication.
