Remove the Convex AMO strategy from the OETH Vault

[clement-ux]

Summary

Removes the Convex OETH/ETH AMO strategy (0x1827F9eA98E0bf96550b2FC20F7233277FcD7E63 — ConvexEthMetaStrategyProxy / addresses.mainnet.ConvexOETHAMOStrategy) from the OETH Vault through a governance proposal. The old Curve OETH/ETH pool used by this AMO is no longer used.

The proposal performs a single action on the OETH Vault:

• removeStrategy(0x1827F9eA98E0bf96550b2FC20F7233277FcD7E63)

removeStrategy withdraws all assets from the strategy back to the Vault (and reverts if any non-dust balance remains) before marking it as unsupported, so no separate withdrawal action is needed.

No new contracts are deployed — this is a governance action only.

Verified by running the full deploy chain on a mainnet fork (FORK=true pnpm run node:fork): the proposal is submitted, voted, queued and executed on the OETH Vault without revert.

Deploy checklist

Two reviewers complete the following checklist:

- [ ] All deployed contracts are listed in the deploy PR's description
- [ ] Deployed contract's verified code (and all dependencies) match the code in master
- [ ] Contract constructors have correct arguments
- [ ] The transactions that interacted with the newly deployed contract match the deploy script.
- [ ] Governance proposal matches the deploy script
- [ ] Smoke tests pass after fork test execution of the governance proposal
