integration donor survey when a user makes a successful donation

[divine-comedian]

we have made the donor survey 2025 in typeform

https://giveth.typeform.com/donorsurvey2025

Design

We would like to make this available on the dapp for donors to see and fill out, providing critical insights into the giveth product(s).

This should show either embedded into the donation success page or a pop-up modal on top of the same page

Development

Users that have already completed the survey should not see it again for a minimum of 2 months
There is a 40% chance the survey will appear for every eligible successful donation

We should avoid needing to make any changes in the back-end and instead rely on user's local storage.

donor survey responses are handled by typeform and collected in a google spreadsheet.
if a user's clears their local storage we treat them as if it's a first time user/donor and have 40% chance of seeing the survey again

nice to have: if for whatever reason we cannot access a given user's local storage we reduce probability of survey appearing to 10%
