feat: add tooltips to category selection buttons

[Pratiyankkumar]

Description

Added tooltips to category selection buttons in the mail interface that appear when hovering over inactive buttons. This improves UI discoverability by displaying the category name above each icon, helping users understand the purpose of each button without needing to click it first.

Walkthrough

The renderCategoryButton function within the CategorySelect component was refactored to distinguish between overlay and non-overlay button rendering. For non-overlay buttons, tooltips are now provided for unselected categories, and click handlers update the category and search value. Overlay buttons are rendered without interactive handlers or tooltips and are set as visual-only elements. The assignment of the activeTabElementRef was also simplified to depend solely on the selected category. No changes were made to exported or public entity declarations.

Changes

File(s)	Change Summary
apps/mail/components/mail/mail.tsx	Refactored renderCategoryButton to provide tooltips and click handlers for non-overlay buttons, and to render overlay buttons as visual-only; simplified activeTabElementRef assignment.

Poem

In the warren of code, with buttons anew,
Tooltips now sparkle for each unselected view.
Overlays stand silent, just there for the show,
While bunnies refactor, letting clarity grow.
With every click and hover, the categories gleam—
A hop, a skip, and a tooltip dream! 🥕
