Optimise plot lines

[Estasie]

This PR refactors the plotLinesPlugin to improve performance.
Key improvements:

• Replaced deepIsEqual checks with simple id-based comparisons for plot lines.
• Switched from array-based storage to a Map, reducing the complexity of operations like addition, removal, and updates to O(1) where applicable.
