Display current date instead of “Today” + prevent adding empty tasks

[notriyaverma]

• ** Currently, the to-do list app shows a static title “Today” on the top of the page.
  It would be more dynamic and user-friendly if it displayed the current date (e.g., “Thursday, November 6”) automatically.

• Additionally, the app currently allows adding empty tasks, which results in blank entries in the list.
  A validation check (both front-end and back-end) should prevent this and show a small popup or message like “⚠️ Empty task!” when users attempt to add an empty input.**

Expected Behavior:

1. The header dynamically shows the current date.

2. When the add (+) button is clicked with an empty input:
   No new task is added.
   A popup or small message appears saying “Empty task!”.

Current Behavior:

The header always displays “Today”, regardless of the actual date.
Clicking the add (+) button with an empty field still adds a blank task to the list.

Proposed Solution:

• Modify the Express route to pass the formatted current date to the EJS template.

• Add front-end validation (JavaScript) to block submission of empty inputs.

• Add a small error message element under the input box for user feedback.

• Optionally add a server-side check to ensure data integrity.
