Fix dependency array in RouteValidationWrapper causing loop (#51170)

## Context

For staging and local only, if you opened the a table in the table
editor, then navigate out, and back into the table editor - the browser
freezes
- The TableEditor itself has a `useEffect` that reads that and redirects
to the last visited table when landing on `/editor`
- `router` is in the dependency array which for the TanStack build is
not a stable singleton, resulting in a redirect loop - so the main fix
was to remove `router` from the dependency array
- (Unrelated) Also cleaned up some logic in the redirect regarding
reading the tab ID

## Summary by CodeRabbit

* **Bug Fixes**
* Improved table editor redirects so they select the matching open table
tab from history or fall back to the first open table tab when
available.
