This PR polishes off the channel buttons such that they behave as
expected.

The absolutely-positioned button container will now no longer take up
space—and thus obscure the channel name—when there are no notifications
and the channel entry is not hovered.

Tab bar was losing focus for one frame which led to it skipping rendering of tab controls & flickering. It also occured when opening new tabs.

After talking with Max, we decided to bring back the debounce time to
the telemetry queue, only, with a longer duration than before.

This reverts commit 09951208a78c9933159c68c6f8105eda40e8bd7e, reversing
changes made to 93a818d0186dce098cae4ae08dd368c23b895a4b.

I noticed an issue where context menus were appearing in the wrong
location (shifted to the right) as a result of this change.

This PR is another pass at improving the positioning of channel buttons.

I had to employ some dirty hacks to get it to work, but I think it is
~mostly there.

For now, we'll need to deploy to `nightly` manually, using the same
scripts that we use to deploy to `preview` and `production`.

We've renamed the `deploy` script to `deploy-collab`, and added a new
script, `deploy-postgrest` that sets up the Postgrest database admin
API. We split that out, since it's not needed for environments that
share a database with prod.

Also, move postgrest service + deployment into a separate manifest
file, which is deployed via a separate script, `deploy-postgrest`.
This way, we don't have unused postgrest instances in preview and
nightly, since those use the prod database.

Adds the infractucture for settings events and specifically tracks theme
settings. Currently, we only take note of the theme at app open and when
the user switches the theme with the theme selector. Changes at the
config file are ignored, as putting code that low leads to a lot of
chances of reporting theme events when the user hasn't done anything.
This change is done in both Zed 1 and Zed 2.

I'll open up a PR on zed.dev and adjust the database accordingly.

There was a hypothesis that this would fix border rendering.

It doesn't :D; but it does at least mean that they are always
consistently
broken, so it may be easier to fix.

This PR adds additional background and border colors for each of the
status colors to the theme.

These colors are then used to style the diagnostic popovers:

This PR restores the semi-transparency to the scroll bar handle colors
that were lost in #3842.

If we adjust the rendering of the scrollbar to draw the status
indicators on top of the scrollbar handle then we can remove the
transparency.

Bring Zed1 themes closer to their old appearance using the `base_theme`
values.

This will inevitably re-introduce some outstanding design issues from
Zed 1 that we will need to solve (low contrasts in some places, etc.)
We'll work on some of these in a later PR.

Known issues introduced:
- Scrollbar thumb is incorrectly drawn in front of the indicators
- Borders aren't quite correct - will fix in a followup
- Titlebar/status bar buttons will now have low contrast states
- Keybinding background color blends with palette

There are likely more issues, add them to the product checklist as you
find them.

- N/A

This PR absolutely positions the channel buttons on top of the channels.

This prevents the buttons from getting pushed off the edge of the panel
when the channel names are long.

Still needs some fine-tuning, but gets us closer to where we want to be.

It's not quite complete, but we gotta start somewhere.

Previously, we changed borders to be drawn after content, so they are no
longer part of the same quads as the background. In our change, we gave
the background quad a transparent black border and the border quads
transparent black backgrounds. However, this caused the other channels
to blend toward that black color before becoming fully transparent,
causing them to become darker.

In this PR, I source the "placeholder" color by duplicating the values
for the other channels and only adjust the alpha down to zero.

Release Notes:

This makes it a bit more approachable to implement.

This required converting the state of Component to AnyElement, which
costs an allocation. I'm hoping this will be ok performance-wise now
that AnyElements use bump allocation, but I need to benchmark still.

This PR maps the suggestions colors from the Zed1 themes to the Zed2
themes.

This PR adds general-purpose functions for obtaining a `Length` in
viewport units.

Previously in #3600 we had added specific variants of `w` and `h` that
took viewport units, but I think it makes more sense to just have a
primitive that can compose with any styling method that accepts a
`Length` or `Into<Length>`.

This PR increases the max height of the outline picker so that it can
take up a larger area of the screen when there are lots of results.

This behavior is similar to the way it was in Zed1.

The word "new" is shorter and blends in with `new` constructors that are
