Categories/Tags for Saved Leads |Major UI overhaul, functional bug fixes, and category-based lead management

Fix #8

This PR introduces a significant upgrade to both the functionality and design of the LinkLeads Chrome Extension.
I have worked extensively on enhancing JavaScript logic, fixing critical bugs, and delivering a more modern, user-friendly UI.

Key Improvements

• UI Revamp

  • Applied a modern gradient background and improved typography.
  • Redesigned input fields, buttons, and lead items with rounded edges, hover effects, and better spacing.
  • Added visually appealing category headers for grouped leads.

• New Features

  • Introduced Category Input when saving a lead (both via "Save Input" and "Save Tab").
  • Implemented a Category Filter Dropdown to quickly filter leads.
  • Grouped leads by category in the display for better organization.

• Functional Fixes

  • Delete All Button now works reliably and clears UI instantly.
  • Fixed inconsistent behavior in saving leads and retaining data across sessions.
  • Ensured backward compatibility by migrating older saved data to the new format.

How to Test

1. Save a lead with a category.
2. Save another lead without a category (defaults to 'Uncategorized').
3. Use the category filter to switch between categories.
4. Double-click the "Delete All" button to clear all leads instantly.

Impact

This update makes the extension far more organized, visually appealing, and functional, ensuring a better user experience for managing saved leads.
