update project status based on verification points

[divine-comedian]

From #1740 we should handle updating a project's status based on how many verification points it has.

Currently we have three statuses to consider:

• Unverified
• Level 1
• Level 2

Projects must have a certain amount of points to move past unverified and become eligible for further levels.

Verification level 1

In order to obtain level 1 a project must have 3 verification points. Projects with level 1 are considered verified=true in the project data. they get access to GIVpower but do not yield GIVbacks to their donors.

Verification level 2

In order to obtain level 2 a project must have 20 verification points AND they must have submitted an Impact Audit (Project verification form status = submitted.

Projects with level 2 are considered isGivbacksEligible=true in the project data. they get access to GIVpower AND yield GIVbacks to their donors.

Ideally we can handle checking this data real-time as the DeVouch indexer processes on-chain events. If we are not able to handle real-time events then a delay of up to 12 hours is acceptable.

Requirements

• The number of points required to reach each level can be easily changed by a developer
• when a project has equal or greater verification points to the level 1 threshold the project's status changes to "Level 1"
• when a project has equal or greater verification points to the level 2 AND submits an Impact Audit threshold the project's status changes to "Level 2"
• If a project's loses points and it falls under a given threshold then the project's status downgrades correspondingly
  • if it has 3 or more points & falls under 3 points it goes from level 1 -> unverified
  • if it has 20 or more points & falls under 20 points it goes from level 2 -> level 1
