Title: Show "Daily Data Refresh in Progress" banner during scheduled dashboard rollup execution

Type: Enhancement
Priority: Medium

Background:
The system executes scheduled rollup jobs daily between 12:01 AM and 12:15 AM IST to calculate and refresh dashboard analytics.

Schedulers involved:
- analytics-rollup
- advanced-analytics-rollup
- tenant/summary-rollup

During this period, dashboard widgets, reports, and analytics may display incomplete or outdated data until processing is completed.

Requirement:
Display an informational banner on the dashboard while the daily rollup jobs are running.

Banner Title:
⚙️ Daily Data Refresh in Progress

Banner Message:
Your dashboard is currently being updated as part of our scheduled daily data refresh (12:01 AM – 12:15 AM IST). During this time, analytics, reports, and summary metrics may temporarily display incomplete or outdated data. Please refresh the dashboard after 12:15 AM IST for the latest information.

Display Conditions:
- Show the banner between 12:01 AM IST and 12:15 AM IST every day.
- Automatically hide the banner after 12:15 AM IST.
- Display the banner on all dashboard pages that consume rollup data.

Functional Requirements:
- Show the banner only during the scheduled rollup window.
- The dashboard should remain accessible.
- Existing APIs should continue functioning normally.
- Users should still be able to navigate the application.
- The banner should disappear automatically after the rollup window.

Acceptance Criteria:
- Banner is visible only between 12:01 AM and 12:15 AM IST.
- Banner is hidden outside the scheduled window.
- Users are informed that analytics and reports may temporarily be incomplete.
- There is no impact on existing dashboard functionality.
- Banner styling follows the application's standard information/notification design.

Expected Outcome:
Users clearly understand that temporary discrepancies in dashboard metrics are due to the scheduled daily rollup process rather than a system issue.
