This commit allows the ProseMirror rich editor to display chat
transcripts copied from chat using the "Copy" button.
The BBCode usually looks something like this:
```
[chat quote="hunter;29856;2025-03-20T07:13:04Z" channel="design gems 🎉" channelId="95"]
haha **ok** _cool_
[/chat]
```
But there are several variations that must be accounted for:
* Single message from single user
* Multiple messages from a single and multiple users
* Messages inside chat threads
The rich transcript extension has to ignore many of the chat transcript
markdown
tokens because they simply aren't necessary -- none of the ProseMirror
nodes need
to be editable. So, we basically recreate the same HTML that the chat
transcript markdown
rule does in the `toDOM()` function. Maybe in future we want to make the
markdown rule
do less and have this HTML creation in one place, but for now we need to
mirror in both files.

When copying images from cooked, we have a `data-base62-sha1` attribute
instead of a `data-orig-src` that we were expecting.
This PR fixes it and adds a system test.
Continues the work done on
https://github.com/discourse/discourse/pull/30815.
Extends the ProseMirror-markdown `code-block` node by integrating our
existing HighlightJS pipeline for code highlighting and adding a node
view with a `<select>` to change the language of the block.
We're also adding the markdown paste extension, which handles converting
pasted text/plain to rich content if it contains Markdown.

Tries to fix the composer upload spec by making the upload
slow enough to allow clicking the Cancel button, and improves
generally the API for CDP network changes.
This commit introduces a ChatChannelPaneSubscriptionsManager
and a ChatChannelThreadPaneSubscriptionsManager that inherits
from the first service that handle MessageBus subscriptions
for the main channel and the thread panel respectively.
This necessitated a change to Chat::Publisher to be able to
send MessageBus messages to multiple channels based on whether
a message was an OM for a thread, a thread reply, or a regular
channel message.
An initial change to update the thread indicator with new replies
has been done too, but that will be improved in future as we have
more data to update on the indicators.
Still remaining is to fully move over the handleSentMessage
functionality which includes scrolling and new message indicator
things.
