This PR fixes an issue where the outer `ListItem` element was using a
static ID instead of the one provided to the component.

Now that active states are fixed, this meant that any time there were
sibling list items they would share active states if one of them was
clicked.

Release Notes:

- N/A

This PR removes the left-click filtering from the `on_click` handler for
`ListItem`s.

It's no longer needed after #3584.

This PR implements the `VisibleOnHover` trait for `IconButton`s.

I noticed that in a lot of places we were wrapping an `IconButton` in an
extra `div` just so we could call `visible_on_hover` on it. By
implementing the trait on `IconButton` directly it allows us to avoid
the interstitial `div` entirely.

Release Notes:

- N/A

This PR adds a `.visible_on_hover` helper method that can be used to
make an element only visible on hover.

I noticed we were repeating this similar stanza in a bunch of different
spots:

```rs
some_element
    .invisible()
    .group_hover("", |style| style.visible())
``` 

so it seemed like a nice thing to factor out into a reusable utility.

This PR reworks the `ListItem` and `ListHeader` components to use
slot-based APIs, making them less opinionated about their contents.

Splitting this out of the collab UI styling PR so we can land it to
avoid conflicts.

This PR wires up the tooltips on the actions in the tab bar.

This PR fixes an issue where the tab bar drop target was not receiving
any size.

The styling isn't 100% correct yet, as the updated background color has
a gap around it.

This PR fixes the styling of the project search tabs.

We now have spacing between the icon and the tab label, as well as use
the correct color for the icon based on whether the tab is active or
not.

This PR fixes an issue where we would sometimes have extra blank lines
in the completions menu.

This was due to some items including documentation labels that were
empty strings.

- Bump LiveKit client version.

This PR updates the buffer search to deploy to a second row in the
toolbar, instead of trying to deploy into the initial row.

This is the same way it works in Zed1.
