Includes ChannelsTable, RedemptionsTable and UsersTable:
• Refactor `refresh(page = activePage)` in all three tables so data reloads the requested (or current) page instead of forcing page 1.
• On single-row deletion (and bulk deletion in ChannelsTable):
– Refresh current page immediately.
– If the refreshed page has no data and `activePage > 1`, automatically load the previous page to avoid blank views.
• RedemptionsTable: corrected prior bug where `refresh` used `activePage - 1`.
• Misc: removed outdated inline comments and aligned search / reset flows.
Result: smoother UX—users stay on their working page, and pagination gracefully adjusts after deletions.
