feat: Menu Status Indicator

[CooperWang0912]

PR Description

• Created status indicator for the installation menu

Motivation

• Visually indicate which fields are preventing the user from installing
• Create instant feedback when user configures a field
• Provide better user experience for people unfamiliar with the installation process
• Closes [Feat] Menu Item Status Indicator #4658

Technical Description

1. Added method _get_status_prefix for menu item completion status, with red exclamation marks for required and uncompleted fields, yellow dots for optional and uncompleted fields, and green checks for completed fields.[¹] The checks are achieved using the following logic:

if item.read_only or item.key in (SpecialMenuKey.SAVE.value, SpecialMenuKey.INSTALL.value, SpecialMenuKey.ABORT.value):
			return ''

		if item.key == 'auth_config':
			auth_config: AuthenticationConfiguration | None = item.value
			is_auth_valid = auth_config is not None and (auth_config.root_enc_password is not None or auth_config.has_superuser())
			if is_auth_valid:
				return '[bold green][✓][/bold green] '
			return '[bold red][!][/bold red] '

		# Standard mandatory or configured item check
		if item.has_value():
			return '[bold green][✓][/bold green] '
		elif item.mandatory:
			return '[bold red][!][/bold red] '
		else:
			return '[bold yellow][•][/bold yellow] '

2. Added method _update_item_labels that updates the menu render based on _get_status_prefix. The code is as follows:

def _update_item_labels(self) -> None:
		"""
		Re-applies translated titles and status prefixes to all active menu items.
		"""
		raw_options = self._get_menu_options(wrap_actions=False)
		new_options = {o.key: o.text for o in raw_options if o.key is not None}

		for item in self._item_group.items:
			if item.key in new_options:
				base_title = new_options[item.key]
				prefix = self._get_status_prefix(item)
				item.text = f'{prefix}{base_title}'

3. In order to avoid stale feedback due to background process not instantly updating values, created a wrapper that calls the _update_item_labels when called, and is triggered with _get_menu_options.[²] The implementation is as follows:

def _wrap_action(self, item: MenuItem, action: Callable[..., Any]) -> Callable[..., Any]:
		@wraps(action)
		async def wrapper(*args: Any, **kwargs: Any) -> Any:
			try:
				if inspect.iscoroutinefunction(action):
					result = await action(*args, **kwargs)
				else:
					result = action(*args, **kwargs)
					if inspect.isawaitable(result):
						result = await result

				item.value = result

				return result

			finally:
				self._update_item_labels()

		return wrapper

Tests and Checks

• I have tested the code!

Notes

[¹] The color scheme and symbols are up for discussion, and changes to these would be fairly straight forward
[²] I am using this primarily to contain the blast radius inside global_menu, and I would be happy to rework the logic if needed
