feat(dropdown): add noMenu input and custom icon support (#599, #601)

[giulio-leone]

Fixes #599 and #601

Problem

1. [Feat] Possibilità di utilizzare il componente <it-dropdown> senza menù #599: The <it-dropdown> component always renders the .dropdown-menu element, even when no menu items are provided. This makes it impossible to use the dropdown button appearance without an attached menu (e.g. to trigger a modal on click).

2. [Feat] Possibilità di personalizzare l'icona (e la sua dimensione) usata dal componente <it-dropdown> #601: The dropdown icon is hardcoded to expand at size sm with rotation animation. Users cannot customize the icon, its size, or disable the rotation.

Solution

Added four new inputs to ItDropdownComponent:

Input	Type	Default	Description
noMenu	boolean	false	Hides the dropdown menu entirely
iconName	IconName	'expand'	Custom icon name
iconSize	IconSize	'sm'	Custom icon size
staticIcon	boolean	false	Disables icon rotation animation

When noMenu is true:

• The .dropdown-menu div is not rendered
• data-bs-toggle="dropdown" and aria-haspopup attributes are removed
• The Bootstrap Dropdown plugin is not initialized
• The button/link still renders normally with full styling

All defaults preserve existing behavior — fully backward compatible.

Usage examples

<it-dropdown [noMenu]="true" (click)="openModal()">
  <span button>Open Modal</span>
</it-dropdown>

<it-dropdown [iconName]="'it-settings'" [iconSize]="'lg'" [staticIcon]="true">
  <span button>Settings</span>
  <it-dropdown-item list>Option 1</it-dropdown-item>
</it-dropdown>

Verification

• ✅ 135/135 tests passing (26 new tests)
• ✅ 0 lint errors (8 pre-existing warnings)
• ✅ Double gate passed (2 consecutive clean runs)
• ✅ Works in button, link, and nav modes
• ✅ Combined features work (noMenu + custom icon)

⚠️ This reopens #638 which was accidentally closed due to fork deletion.
