Consolidate tab persistence logic into Tabs component

- Move active tab persistence into Tabs component with storageKey + activeTabKey props
- Change value prop to defaultValue so callers don't manage tab state
- Add TabsRef with setActiveTab method for programmatic tab switching
- Restore request_pane.focus_tab listener for :param placeholder clicks
- Update all Tab consumers to use new pattern
