[SWIP-36] Clean Up VaultRegistry, Remove Inactive Relay, Fix Rounding Error in Boost

In this proposal, we’re seeking DAO approval to remove previous Ethereum and Gnosis Chain factories from the VaultRegistry contracts on both chains, remove the Eden Network relay from the list of approved relays for the smoothing pool, and reduce the default Aave borrow LTV in Boost by 0.0000001% fix a rounding error that prevents users from depositing less than 0.06 osETH into Boost.

These changes are part of the upgrade deployment routine, can be considered administrative, and do not introduce changes in the protocol logic or new contracts.

For the full details of this proposal please consult the forum post.
