Clients:
- Replace Previous/Next buttons with a "Show N entries" dropdown
(25/50/100/200, persisted to localStorage) and numbered page selection
with prev/next chevrons and ellipses for long ranges.
Syslog (Network Services):
- Drop the Single Device / All Devices mode toggle; always show the
fleet-aggregated view with coverage badges.
- Add a per-section device dropdown + "Add to device" button beside
"Add to All Devices" for targeting a single device (direct save).
- Edit / enable-disable / remove remain coverage-scoped, so single-device
management is preserved without the separate mode.
