Oracle Upgrades

[0x4007]

This can be looked into in late 2024/early 2025 but we should consider a more robust oracle strategy. Chainlink is not very good for censorship resistance.

@rndquu @gitcoindev @molecula451 I have concerns around using Chainlink and censorship resistance. Chainlink is a centralized point of failure for the protocol. Why not use the on chain TWAPs instead? Perhaps we can have a planned upgrade sometime in late 2024 to change the oracle(s)?

We'll gradually move to smth like "take the median price from chainlink, curve, uniswap, other oracle provider". Right now chainlink is the fastest to implement, safest and most reliable solution.
