fix: always update normal powerlevel when switching regions

[Copilot]

The normal powerlevel field was not being updated automatically when switching RF regions in the Controller node panel. Users had to manually click the refresh button to see the updated powerlevel value after changing regions, while the LR max power field was updating correctly.

Root Cause

The setRFRegion() method in ZwaveClient.ts only refreshed the normal powerlevel when it was configured in 'auto' mode:

// If powerlevels are in auto mode, refresh them after region change
if (this.cfg.rf?.txPower?.powerlevel === 'auto') {
    propsToUpdate.push('powerlevel')
}

However, the normal powerlevel should always be refreshed when the region changes because:

• The controller node caches this information
• Legal power limits may change based on the RF region
• The cached values need to be re-read from the controller

Solution

Modified the setRFRegion() method to always include 'powerlevel' in the properties to update when the region changes:

const propsToUpdate: Array<'powerlevel' | 'RFRegion' | 'maxLongRangePowerlevel'> = 
    ['RFRegion', 'powerlevel']

// If LR powerlevel is in auto mode, refresh it after region change
if (this.cfg.rf?.maxLongRangePowerlevel === 'auto') {
    propsToUpdate.push('maxLongRangePowerlevel')
}

This ensures that both normal and LR powerlevels are properly updated when switching regions, matching the expected behavior described in the issue.

Testing

Added comprehensive tests to verify:

• Normal powerlevel is always updated when region changes
• LR powerlevel is only updated when in auto mode (preserving existing behavior)
• Error handling when driver is not ready

Fixes #4377.

💡 The pull request title does not match our guidelines 💡

We follow conventional commits, check out the description and examples. This means that the PR title must...

• start with the type of change, e.g. feat:, or fix:
• optionally specify a scope, for example we use config for changes to config files: feat(config):
• contain a description that explains what is being changed, e.g. add a parameter, correct a typo, ...
• and ideally explains what the change affects, e.g. the device (manufacturer, device label, firmware, ...)

The description should use uppercase and lowercase normally, except for the first character which must be lowercase.

The change seems wrong

[robertsLando]

@AlCalzone apart from the ci test added the change on code seems legit, why you said it's wrong?

Because it's supposed to refresh the powerlevel when it's configured automatically. This change just makes it refresh it always, but I already had it set to auto powerlevels.

[robertsLando]

So the previous implementation was correct the question so is why it's not updated ? Could it be a race condition? Maybe when it reads it it's still not updated

I debugged. rf.txPower.powerlevel is an empty string, but autoPowerlevels is set:
