Profile page: empty state glitches on Atmosphere account loading

[alex-key]

Describe the bug

When user has 0 likes and Profile page reloads empy state is shown for less than 1 second and disappears after user data is loaded.

• Add loading state to prevent this glitch.
• Improve like widget render with added loading state, so it does not glitch when user has liked packages: 0 -> X (see recording below)

Steps to reproduce:

• Go to https://npmx.dev/profile/[YOUR_HANDLE]
• Remove all your likes (sic!)
• Reload page
• Empty state glitches (<1s)
