Describe the bug
Using a data_generator, the current value of the entity is displayed wrong, since always the last / youngest historical value is used for this according to the code.

apexcharts-card/src/graphEntry.ts

Lines 113 to 114 in 1449c7f

	get lastState(): number | null {
	return this.history.length > 0 ? this.history[this.history.length - 1][1] : null;

In case a data_generator is used which creates "future" values (values which will be valid in a future point in time) - this approach causes the issue:

Version of the card
Version: 2.0.2

Expected behavior
The value of the entity as reported by HA should be used the display the current value
