[Epic] Contract emergency upgrades

[emizzle]

We need to investigate how to deploy the contracts. This also includes setting up architecture for contracts upgrades.
The key part is to set up the architecture in a way so that we can ensure the handling of emergencies.

• investigate / research existing solutions

• Discussion context (not work): Handling emergency scenarios of smart contracts codex-contracts-eth#111

• Contract's monitoring codex-contracts-eth#172

• Refactor contracts to support upgrades codex-contracts-eth#173

• Consultation with legal: approval for #173

• Emergency preparedness protocols/drills: normal and emergency situations (both proactive and reactive emergencies)

• Suggested Vault API changes #155

Note: moved chain reorg task here and added estimate to this epic's total (15 days)
Note: add Linea deployment to estimate (5 days)
Note: moved deployment tasks to #151
Note: 10/12/24 -- time estimate does not include emergency preparedness protocols/drills (80 days). Emergency preparedness estimate is 12 days.
