fix: cleanup useKebabMenu code (#24042)

Refactored the tab overflow hook by renaming `useTabOverflowKebabMenu`
to `useKebabMenu` and removing the configurable `alwaysVisibleTabsCount`
parameter.

- Renamed `useTabOverflowKebabMenu` to `useKebabMenu` and moved it to a
new file
- Removed the `alwaysVisibleTabsCount` parameter and hardcoded it to 1
tab as `ALWAYS_VISIBLE_TABS_COUNT`
- Removed the `utils/index.ts` export file for the Tabs component
- Updated the import in `AgentRow.tsx` to use the new hook name and
removed the `alwaysVisibleTabsCount` prop
- Refactored the internal logic to use a more functional approach with
`reduce` instead of imperative loops
- Added better performance optimizations to prevent unnecessary
re-renders
