Filter cache runs by date range on the Tuist server

The cache runs listing API now supports filtering by execution window. You can pass a ran_at query filter object with gt, gte, lt, and lte operators using Unix timestamps in seconds to ask for cache runs within a specific date range, without having to paginate the full history. Existing git reference, branch, commit, and pagination filters keep working alongside the new range filter. Out-of-range or negative timestamps are rejected with a clear bad request response, and the regenerated Swift command-line client exposes the new typed filter payload and surfaces those validation errors. Cache run responses now report their actual ran_at value rather than deriving it from created_at.
