feat(EntityGrid): Split contacts into recent and alphabetical sections

When displaying contacts (not search results), show the 3 most recently
added contacts at the top with a "Recently Added" heading, followed by
the rest sorted alphabetically with an "Everyone Else" heading.

- Add recentContacts and alphabeticalContacts computed properties
- Hide "You" and "Unnamed" special entities during search
- Only show search spinner when actively searching with a term
- Style section headings with uppercase, improved spacing, and borders
