🐛 fix(ui): prevent pagination flicker when tables have no data

Fix pagination component flickering issue across multiple table views
by initializing count states to 0 instead of ITEMS_PER_PAGE. This
prevents the pagination component from briefly appearing and then
disappearing when tables are empty.

Changes:
- usage-logs: logCount initial value 0 (was ITEMS_PER_PAGE)
- users: userCount initial value 0 (was ITEMS_PER_PAGE)
- tokens: tokenCount initial value 0 (was ITEMS_PER_PAGE)
- channels: channelCount initial value 0 (was ITEMS_PER_PAGE)
- redemptions: tokenCount initial value 0 (was ITEMS_PER_PAGE)

The createCardProPagination function already handles total <= 0 by
returning null, so this ensures consistent behavior across all table
components and improves user experience by eliminating visual flicker.
