feat: Add Profile Search, Visibility Controls, and Updated Search UI

Summary

This PR adds profile search and profile visibility controls to the user dashboard, along with an updated search UI and navbar styling fixes.

Changes

Profile Search

• Added a search bar to the navbar when users are inside their profile dashboard.
• Users can search for profiles by name or wallet ID.
• Name searches use a similarity score, allowing relevant profiles to appear even with spelling mistakes.
• Updated the search UI to separate similar results from direct matches.
• Wallet IDs are only partially displayed in search results.
• Public profile information is stored separately from private wallet data for improved security.

Profile Visibility

• Added a toggle allowing users to show or hide their profile from other users.
• Each visibility change requires a wallet signature to verify wallet ownership.
• Hiding a profile removes its record from the public profile table.
• Success and error messages are displayed in the general update text section.
• Added appropriate toggle colours for both light and dark mode.
• The toggle design can be further improved in a future update.

UI Fixes

• Fixed navbar formatting inconsistencies between the home page and dashboard.
• Improved the profile search UI and handling of similar search results.

  • Exact names
