I added modifiers, replaced the desmos embed, and added an hour calculator!

• For the modifiers, I just made it change the min and max mult. I was originality going to make the modifiers a separate variable in the formula, but that would be unnecessarily complicated compared to just changing the min and max.
• The new graph is mostly vibe-coded because I couldn’t find any graphing libraries that I liked, and I don’t have time to learn to make it myself (im busy with other projects)
• The hours calculator was really easy because I basically just duplicated the percentile<->mult calculator component and tweaked it slightly
