Pane(fix[copy_mode]): -q cancels modes, -e exits on scroll to bottom

why: copy-mode -q cancels all modes (window_pane_reset_mode_all), not
"quiet". And -e exits copy mode when scrolling reaches the bottom of
history, not "exit on copy". Verified in cmd-copy-mode.c and tmux
manpage. Internal tmux name for -e is scroll_exit.
what:
- Rename quiet param to cancel
- Rename exit_on_copy param to exit_on_bottom
- Update docstrings to reflect actual semantics
