Fixes
https://linear.app/zed-industries/issue/Z-1510/join-project-notification-takes-up-full-screen-on-a-second-monitor

There were multiple mistakes in the positioning of Zed's notification
windows, one of which lead to the notifications taking up the full
screen on secondary displays 😱 .
* Wrong sign for the vertical padding (moving the window *upward*
instead of downward)
* Using the screen's full frame instead of its "visible frame" (which
accounts for app menu bar)
* Wrong coordinate translation between our coordinates and AppKit's
coordinates. Regardless of which display a given window appears on, the
coordinate translation needs to use the height of the *main* display.

Release Notes:

- Fixed a bug where call notifications were accidentally full-screen on
all displays except the main display.

Adds 'a'/'i' in visual mode

Changing mode almost always introduces the (1 selected) text in
the status bar, so we may as well also keep the --'s for block and line
mode.

(reported as vim feedback, but really true of the editor too)

This diverges from vim's behaviour (which collapses the
cursor to a single point on undo).

This fixes a bug where opening and closing command would reset your
selection incorrectly.

This reverts commit ab9356e9d83635978a1cb305d4f017f9a1d57dec.

Tailwind needs user languages and language-to-language-id mappings to
start providing completions for those languages.
And also it has emmet completions disabled by default, enable them.

This will also fix the bug that @JosephTLyons observed where accepting a
channel invite would not show sub channels.

Release Notes:

- Offline section is now collapsed by default
- Manage members now shows full list
- Dragging of docks now follows the mouse exactly, and double clicks
reset size. (https://github.com/zed-industries/community/issues/1816)

Closes
https://linear.app/zed-industries/issue/Z-2735/make-inlay-hints-discoverable
Deals with https://github.com/zed-industries/community/issues/1764

Adds `editor::ToggleInlayHints` command and a new panel with two
buttons for 
* toggling hints on/off for every editor separately (overrides settings)

Would benefit from a new icon.

* toggling buffer search on/off 

Does not have a keybinding shown in its tooltip, that is a separate
issue with the way `KeystrokeLabel` gets these for panels not in the
view directly.

Release Notes:

- Adds `editor::ToggleInlayHints` command and a bar to toggle
editor-related items
