Summary

1. Use the new auction's native minimumPrice check instead of checking locally and tending to reset
2. Use the new auction's governanceOnlyKick to ensure only the strategy can kick
3. Claim SP rewards on a report

Changes

1. Remove CHAINLINK_ORACLE, CHAINLINK_ORACLE_HEARTBEAT, and _isAuctionPriceTooLow() logic from Strategy
2. Delete AUCTION_PRICE_TOO_LOW_BUFFER_PCT_MULTIPLIER constant
3. Add AUCTION.setMinimumPrice() call in _tend() to set floor price per auction
4. Enable AUCTION.setGovernanceOnlyKick(true) on deployment
5. Claim SP rewards on _harvestAndReport to ensure those are realized in a timely manner (previously we were counting on rewards to be claimed through a tend or withdraw)
