refactor(notifications): drop dismissed-state machinery; pending = visible

Set mako default-timeout=0 so notifications stay until acted upon. With
auto-timeout off, mako's list IS the pending set, so the
$XDG_RUNTIME_DIR/mako-dismissed bridge becomes dead weight.

- mako/config: default-timeout=0; drop redundant [urgency=critical]
  default-timeout=0 override.
- Delete dismiss-visible.sh and restore-pending.sh; sway calls makoctl
  directly (Mod+n=dismiss, Mod+Shift+n=dismiss --all,
  Mod+Ctrl+n=restore as undo).
- Shrink mako-status.sh to a 20-line counter of makoctl list.
- Rename mako-history.py -> notification-picker.py; lists only
  visible, dismisses via makoctl dismiss -n <id>.
- Update waybar config.jsonc on-click path.
- Update KEYBINDS.md wording (no more 'marks seen' / 'pending set').
