Check existing components (like Select or Tab Bar) and add events where they are missing

[thrbnhrtmnn]

Description

This ticket came after implementing #339 , we should look at more components and check if we also need to change them.

---

Acceptance Criteria

• For the Tab Bar: The component should emit an event or trigger a callback function whenever the active tab changes, allowing other parts of the application to respond to the switch.

---

Background information

• There are more tasks for adding missing events already:
  • TabBar - add missing events #478
  • Radio - add missing events #479
  • Slider (single & two values) - add missing events #480
  • NumberInput - add missing events #481
  • TextInput - add missing events #482
  • Select - add missing events #483
  • RadioGroup - add missing events #484
  • TextArea - add missing events #485
  • TextButton & IconButton - add missing events #486
  • Checkbox - check if events are missing and add them #504
  • ToggleSwitch - check if events are missing and add them #505
• Components without a task:
  • All internal components (Counter, FormLabel, FormCaption)
  • Icon
  • Divider
  • Loader
  • Tooltip (will be added with refactoring)
