Feat: add vote indication under governance

[eDimka]

Hi guys,

Any chance you could add a "You've voted: XXX" on the governance page at least for the active proposals?
to avoid double voting, or knowing the vote has changed after you change your mind on an active proposal

Hi @eDimka, and thank you for the issue! We are going to add this to our roadmap :)
