[FEATURE] Show error overlay for moderator buttons (Resolves DGDG-586)

[mandres-digix]

Ref: DGDG-586, DGDG-311

This applies the same functionality as the changes in PR #106, but for moderator buttons. Project actions are not allowed in the locking phase, so this will prevent users from wasting gas.

Test Plan

• Create a project as a participant during the main phase.
• Teleport to the locking phase: npm run teleport:locking_phase
• Load a moderator wallet
• Verify that endorsing or approving a project will show the error overlay if any of the following conditions are true:
  • User is in the locking phase
  • User is not KYC'd.
