Apply the terminal tag to Omarchy's own terminal windows (#6561)

* Apply the terminal tag to Omarchy's own terminal windows

Omarchy launches TUIs and its own terminal windows under dedicated
app-ids (org.omarchy.btop, org.omarchy.terminal, TUI.float, ...), so the
class never matched the terminal that drew the window and those windows
went untagged.

Also drop the tag's opacity rule, which stripped default-opacity only to
re-apply the identical value. Themes still override through the tag.

* Match terminals by tag for universal clipboard shortcuts

The binding kept its own list of terminal classes, so SUPER + C in a TUI
window sent CTRL + C instead of CTRL + Insert. Read the terminal tag
instead of duplicating the definition.
