feat: update onboarding flow to align with audit-worker config-free execution

[tkotthakota-adobe]

https://jira.corp.adobe.com/browse/SITES-45860

Following the recent audit-worker change that allows audits to run regardless of configuration state, the onboarding flow no longer needs to enable audits in the global configuration before triggering them.

• Audit enable is now gated to scheduledRun=true only — enabling in config is only needed for recurring scheduled runs; one-shot onboards rely on the audit-worker firing without a config entry
• Fixed auditTypes in disableImportAndAuditJob taskContext — was hardcoded to [], now correctly passes the full profile audit type list so the task processor can clean up any audits that were enabled
• Added exceljs and iso-3166 to ESLint import/no-unresolved ignore list — these installed packages cannot be statically resolved by the ESLint import resolver (same pattern as @octokit/rest)

Bug — Dead code in else if (scheduledRun) (Critical)

File: src/support/utils.js, around line 1814

// Before
} else {
log.debug(All the required audits...);
}

// After
} else if (scheduledRun) { // ← always false here
log.debug(All the required audits...);
}

This block is unreachable. We're in the else branch of if (scheduledRun), so scheduledRun is guaranteed to be false — the else if (scheduledRun) condition can never be true. The debug log will never fire.

Intent is unclear — was the goal to remove the log entirely, or to replace it with a different message for the non-scheduled case? Either way, else if (scheduledRun) here is logically impossible and should be resolved.
