[FEAT] Mimir set to 1 for default streaming and 0 for default single swap
Since most UIs will be using "default swaps" to stream, if there were ever any error in the code specific to streaming, just setting the Default Swap back to Single Swap should fix the problem for most users while it gets patched up.
Setting this Mimir to 0 should also modify /quote to return single swap fees (simulate the single swap) instead of streaming swap fees when quoting default params / no params.
