Improve approximate remaining duration by including a constant time

[phecdaDia]

When crafting lots of HQ low-level items the approximate duration is usually way off, as it does not account for the duration between crafts. E.g. when crafting Cobalt Ingots using Delicate Synthesis, the actual time required may be off by a factor of 2 or more.

Adding a constant time to Artisan/UI/CraftingWindowcs:176

private void OnSolverStarted(Lumina.Excel.Sheets.Recipe recipe, SolverRef solver, CraftState craft, StepState initialStep)
        {
            if (P.Config.AutoMode && solver)
            {
                var estimatedTime = SolverUtils.EstimateCraftTime(solver.Clone()!, craft, initialStep.Quality);
                var count = P.Config.CraftingX && Endurance.Enable ? P.Config.CraftX : 1;
                _estimatedCraftEnd = DateTime.Now + count * estimatedTime;
            }
        }

to

private void OnSolverStarted(Lumina.Excel.Sheets.Recipe recipe, SolverRef solver, CraftState craft, StepState initialStep)
        {
            if (P.Config.AutoMode && solver)
            {
                var estimatedTime = SolverUtils.EstimateCraftTime(solver.Clone()!, craft, initialStep.Quality);
                var count = P.Config.CraftingX && Endurance.Enable ? P.Config.CraftX : 1;
                _estimatedCraftEnd = DateTime.Now + count * (estimatedTime + TwoSecondConstant);
            }
        }

would improve the estimates. Similar fixes would need to be done for other sections.
