Extend the invariant testing of MiniPair (launch 114, this commit; live on Sepolia at 0x898a07c8911f43218c5c2e1b7ae8146026f7e040 and still unused, totalShares() == 0 on 2026-09-27) with properties the existing suite does not cover, then review it.

    Added and reviewed MiniPair.invariantDonations.t.sol, covering all five properties, both deposit branches, failed ETH sends, and rounding boundaries.

    No contract defects were found in these checks.
