Caps Lock/Num Lock indicators do not update until panel is interacted with

### What Happened?

I’ve enabled the Caps Lock/Num Lock indicators in system settings, but they do not show or hide unless I interact with the panel.

### Steps to Reproduce

1. Enable Num Lock
2. See nothing change
3. Click any button in the panel
4. See Num Lock indicator appear

### Expected Behavior

Indicators reflect the keyboard state the moment it changes.

### OS Version

8.x (Circe)

### OS Architecture

amd64 (on most hardwares)

### Session Type

Secure Session (Wayland, This is the default)

### Software Version

Latest release (I have run all updates)

### Log Output

```shell

```

### Hardware Info

_No response_

Start by locating the panel's Caps Lock and Num Lock indicator entry point and reproduce the issue using the listed steps on Wayland. Done means the indicators appear or disappear immediately when the keyboard state changes, without requiring panel interaction.
