BREAKING: This will break old clues and their detection
BREAKING: requires migration because we broke protobufs for shielded pool params.
This fixes the WASM build.
We broke the protobuf for the shielded pool params, by changing the structure of the FMD params, and this migrates that to the default for the new format.

@cronokirby fwiw, the convention is that you write why you expect the Result/Option to be Ok/Some

The first part of #1087.
This restructures the way FMD parameters are handled so that we can choose different algorithms to update the parameters.
A migration has been written so that we move from the old format, where we had a hard-coded parameter, to a new format, where we have an algorithm as a chain parameter, and then update the current FMD parameter over time based on that algorithm. The protobufs are also structured so that we can easily add new algorithms over time, without making a breaking state change.
By default, the algorithm just chooses a constant parameter, so dynamic FMD params are not part of this PR.
