feat: replace swayidle with hypridle for idle management

hypridle pairs with hyprlock, honors idle inhibitors (video/calls no
longer blank or lock the screen), and is config-file driven. Same staging
as before: blank monitors @5m, lock @10m, suspend-then-hibernate @30m.
Locks via 'loginctl lock-session' so the before-sleep lock is deduplicated.
