🔧 Final Fix: Button Signals

The Problem

Your button was showing:

[Input Signal: Botón 2]

Instead of just:

Botón 2

Root Cause: In UiButtonComponent template, signals were not being called with ().

📝 All Signals Fixed in UiButtonComponent

File: libs/libs-ui-core/ui-core/src/lib/components/ui-button/ui-button.component.html

6 Signal Calls Fixed:

1. ✅ type → type() - Button type attribute
2. ✅ disabled → disabled() - Disabled state
3. ✅ loading → loading() - Loading state (2 places)
4. ✅ text → text() - Button text (2 places)

Before:

<button [attr.type]="type" [disabled]="disabled || loading">
  @if (loading) {
    <span class="ui-btn__spinner"></span>
  }
  @if (text) {
    <span class="ui-btn__label">{{ text }}</span>
  }
</button>

After:

<button [attr.type]="type()" [disabled]="disabled() || loading()">
  @if (loading()) {
    <span class="ui-btn__spinner"></span>
  }
  @if (text()) {
    <span class="ui-btn__label">{{ text() }}</span>
  }
</button>
