Fix delete button click propagation in list views

[Copilot]

Description

Delete buttons in list views triggered row click navigation due to event bubbling. Clicking delete would navigate to detail page instead of showing confirmation modal.

Changes:

• Added @onclick:stopPropagation="true" to MudTd cells containing delete buttons in 6 list pages:
  • DeviceModelListPage.razor
  • EdgeModelListPage.razor
  • DeviceListPage.razor
  • EdgeDeviceListPage.razor
  • ConcentratorListPage.razor
  • PlanningListPage.razor
• Corrected MudTh to MudTd in PlanningListPage RowTemplate
• Added test verifying delete click doesn't trigger navigation

Example:

@* Before - click propagates to row *@
<MudTd DataLabel="Delete" Style="text-align: center">
    <MudIconButton OnClick="@(e => DeleteDeviceModel(context))" />
</MudTd>

@* After - click isolated to button *@
<MudTd DataLabel="Delete" Style="text-align: center" @onclick:stopPropagation="true">
    <MudIconButton OnClick="@(e => DeleteDeviceModel(context))" />
</MudTd>

<issue_title>Bug: Delete button doesn't work on device models</issue_title>
<issue_description><!--
Hi there! Thank you for discovering and submitting an issue!

Expected Behavior

Same behavior as devices: Display a modal to confirm, and delete the model if the user confirms

Current Behavior

Clicking on Delete redirects to the model page, which then allows to delete the model with the big delete button.

Steps to Reproduce

1. Click on the 🗑️ button

Context (Environment)

Portal version: 4.13.2.170
LoRaWAN Stack version: 2.2.2

Additional Information

Comments on the Issue (you are @copilot in this section)

@judramos Clicking redirects to the model page only if deletion button is disable (for builtined models). Deletion should not be authorized on the model page in this case. This issue is linked to the [#2856](https://github.com//issues/2856).
