fa9d7d5d20 test: Work around boost compilation error (MarcoFalke)
fa3ecdf778 Revert "build: work around issue with Boost <= 1.80 and Clang >= 18" (MarcoFalke)

Pull request description:

  There seems to be an issue compiling the `chainstatemanager_rebalance_caches` test case with some specific versions of Boost in combination with some specific versions of Clang. For example, Boost 1.74 may fail in combination with Clang 18. [1]

  The error stems from a mixed-type closeness comparison. Given that the comparison is using floating point, and isn't meant to be exact, work around the compile error by ensuring both sides of the comparison are using the same type (`double`).

  This also allows to drop a previous workaround.

  [1] Error:
