[Feature request] probabilities as odds

[Sha-yol]

• Add the ability to input prediction probabilities as odds (e.g. 1:20) instead of fractions. This would be useful, especially for probabilities at the extreme ends of the scale.
• Additionally, allow users to toggle the calibration graph to display odds instead of fractions on the x-axis. To handle potential issues at the edges, either:
  1. Adapt the x-axis range to the actual odds range for each user.
  2. Add zoomed-in subplots for the low and high probability ranges, conditionally displayed when a user has made enough predictions below 10% or above 90%.
