🎨 Palette: [UX improvement] Add context-aware confirmations and ARIA labels

[rauhmaru]

What:
Added descriptive aria-labels to the "Editar" and "Remover" buttons in visualizar.html, visualizar_cocktails.html, and cadastrar_tipo.html. Also updated the delete confirmation dialogs to be context-aware by reading a data-name attribute instead of using direct string interpolation.

Why:
Generic labels like "Editar" or "Remover" are not helpful for screen reader users when scanning a list. Furthermore, generic "Remover este item?" confirmation dialogs leave users unsure of exactly what they are deleting. Injecting the context into the dialog improves confidence and reduces accidental deletions.

Before/After:

• Before: <button>Remover</button> and confirm('Remover este item?')
• After: <button aria-label="Remover Gin">Remover</button> and confirm('Remover Gin?')

Accessibility:

• Added aria-labels to the action buttons in list views so screen readers can properly identify the target of the action.
• Ensured context injection for the javascript confirm box is safe by using data-name to prevent string interpolation errors or vulnerabilities.
