Add info banner for files missing participant or biospecimen associations

[Copilot]

Files can exist without associated participants or biospecimens. When users filter to such files, the summary shows 0 Cases or 0 Biospecimens with >0 Files, which can be confusing.

Changes

• ExploreSummary.tsx: Detect when fileCount > 0 but caseCount === 0 or biospecimenCount === 0, and display a Bootstrap info alert explaining the data gap
• exploreSummary.module.scss: Add styling for the banner

Banner Messages

Condition	Message
0 cases	"Note: Some files are missing associated participant information."
0 biospecimens	"Note: Some files are missing associated biospecimen information."
Both 0	"Note: Some files are missing associated participant or biospecimen information."

Example

{missingInfoMessage && (
    <div className={`alert alert-info ${styles.missingInfoBanner}`}>
        {missingInfoMessage}
    </div>
)}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl96orhu96.us-east-1.aws.clickhouse.cloud
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/htan-portal/htan-portal/node_modules/next/dist/server/lib/start-server.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
