• Added integration for new refund request • Wired up the refunding states based on the new data • Updated code to use strings from libSession instead of hardcoded values • Updated the code to trigger a pro state refresh when the `proAccessExpiryTimestampMs` on the config changes (ie. another device made a change to the pro configuration) • Updated logic to drive mocked pro states via the SessionProManager to make the code a bit cleaner • Updated the handling of pro proofs to sync both active and expired proofs (instead of just active) • Fixed a bunch of warnings
