fix: add clipboard addon to docker container terminal

The docker container terminal did not load xterm's ClipboardAddon, so
pasting into it (e.g. a MariaDB shell) broke the cursor and left the
pasted text uneditable. The web server terminal already loads this addon;
this brings the container terminal in line with it.

Also dispose the terminal on cleanup so its addons don't leak on remount.

Fixes #5065
