feat(waybar): more clickable modules + load avg in CPU readout

- cpu: append 'LOAD {load:0.2f}' (1-min load average) to every state
- custom/wifi: left click toggles iwd Powered via D-Bus (new wifi-toggle.sh)
- custom/notifications: left click opens fuzzel history picker
  (mako-history.sh, previously bound to middle-click); the awkward
  per-click 'makoctl dismiss' is dropped — dismiss-all stays on right,
  restore stays on middle
- clock: left click runs tb-toggle.sh (closest practical proxy for
  'open Calendar tab' — Thunderbird hasn't shipped a -calendar CLI flag
  since Lightning was integrated, so the user lands on whatever tab TB
  was last on)
