fix(tui): disable bracketed paste + mouse capture in panic hook

The panic hook only popped kitty keyboard flags, disabled raw mode,
and left the alt-screen. Bracketed paste (`\e[?2004h`) and SGR mouse
capture (`\e[?1006h`) stayed on, so any panic would leave the user's
parent shell stuck wrapping pastes in `\e[200~…\e[201~` and printing
`\e[<…M` mouse events. Mirror the clean-shutdown teardown so the
shell is fully restored even when the TUI crashes.
