feat(menu): Update menus

[rbarker-dev]

Description

This pull request updates the navigation menus on the profile and projects pages to move several menu items into the profile dropdown and introduces a new mechanism to indicate "under construction" features. It also adds a reusable toast notification for informational messages and a utility to bind "under construction" handlers to menu items.

Navigation and Menu Restructuring:

• Moved "Projects", "Public Gallery", "Paintbar NFTs", and "About" links from the main navigation bar into the profile dropdown menu in both profile.html and projects.html. These dropdown items now include icons for better clarity and visual appeal. [1] [2] [3] [4]
• Renamed the "My Profile" dropdown item to "Profile" for consistency.

Under Construction Feature Handling:

• Added a new bindUnderConstruction utility in toast.ts that attaches click handlers to specified elements by ID, displaying an informational toast when clicked to indicate the feature is not yet available.
• Applied bindUnderConstruction to the "Public Gallery" and "Paintbar NFTs" menu items on both the profile and projects pages, so users receive immediate feedback that these features are under construction. [1] [2] [3] [4]

Toast Notification Enhancements:

• Added a new showInfo function to toast.ts for displaying informational toast notifications, used by the "under construction" handler.
