Add an option to export all history to a text/csv file

[DevBoiAgru]

Problem Statement
Currently, if users want to save their recent calculations for later review or share them with others, the only options are to either screenshot the history pane or copy the result from each history item individually. In addition to being tedious to copy each history item separately, the expression itself is not saved to the clipboard, meaning users must manually type out the expressions.

Evidence or User Insights
I’ve come across several users online questioning why there is no export option for history. Additionally, an issue (#2239) was raised in the repository requesting this.

Proposal
Add a button in the history pane to export all recent history in a human-readable format, such as CSV or TXT.

Goals
Allow users to easily export their recent calculation history to a file in a convenient format.
