Table issues (Filtering, sorting and pagination)

### Current Behavior

* table empties and reloads with every character typed
* when clicking more at the bottom of the table the last entry is shown but the morebutton is still visible & then disappears after 1 more click.
* sorting is client side only (e.g. sorting by name does not reveal the last user Zumba Zulu)

See this comment for more background: https://github.com/flowforge/flowforge/issues/1065#issuecomment-1293357984

### Expected Behavior

* filtering should have a delay after typing (typically 300ms) to avoid flicker.
* table should not be cleared (ideally) when retrieving filtered data (causes flicker)
* when the last entry is shown, the more button should not be visible
* sorting should take into account server side data & show first/last entry in DB not in clients table

### Steps To Reproduce

* add 100 or so users (quick generate users script in [this comment](https://github.com/flowforge/flowforge/issues/1065#issuecomment-1293357984))
* sort users by name
* the last entry shown is only the client side items
* try typing in search, table can be seen to empty and refill each time (flickering)
* try clicking more until `Zumba Zulu` is show - note the more button is still show.
* click the more button one more time - no more records are retrieved but and the button disapears
