chore: increase delay between submitting and voting on proposals

[strophy]

Issue being fixed or feature implemented

Proposals were successfully created but gobject list was empty resulting in gobject vote-many being skipped. Manually checking the proposal count and running the role twice resulted in successful votes, so I think we are just going too quickly here for the slowish P2P governance system.

What was done?

Increase block delay between steps and add 10 second wait just in case
