[Feature request] Support more partiticaption status like needs-action

[Thaodan]

Expected behaviour

Nextcloud tasks should support more participation statuses such as needs action or delegated (#72).
The UI should show something like Status: <Status>

The usage of such an extended status view would be to be able to visualize the status of a task better.
This includes things such as: blocked by another task, waiting and so on.

Actual behaviour

The only supported state right now is the done or undone state portrait by the checkbox next to the taskname.

The app already has the possibility to set the status of a task in the right sidebar:

We offer the following choices for the status:

Lines 423 to 448 in 7536446

	const statusOptions = [
	{
	displayName: t('tasks', 'Needs action'),
	type: 'NEEDS-ACTION',
	icon: 'IconAlertBoxOutline',
	optionClass: 'active',
	},
	{
	displayName: t('tasks', 'Completed'),
	type: 'COMPLETED',
	icon: 'IconCheck',
	optionClass: 'active',
	},
	{
	displayName: t('tasks', 'In process'),
	type: 'IN-PROCESS',
	icon: 'IconTrendingUp',
	optionClass: 'active',
	},
	{
	displayName: t('tasks', 'Canceled'),
	type: 'CANCELLED',
	icon: 'IconCancel',
	optionClass: 'active',
	},
	]

according to RFC 5545, section 3.8.1.11 https://datatracker.ietf.org/doc/html/rfc5545#section-3.8.1.11

In order to support the Participation status according to https://datatracker.ietf.org/doc/html/rfc5545#section-3.2.12 as you propose, we would first need to implement attendees. Without the option to set or invite attendees, it does not make sense to implement a participation status.
