Recalculates time estimates for all items (epics and non-epics) within a project component. This includes:
- Recalculating individual item estimates based on timeFrame and question multipliers/extra hours
- Recalculating epic estimates by summing their children's estimates
- Updating the component's totalTimeFrame
- Respecting visibility conditions (items with invalid conditions are excluded)

Items are processed bottom-up (children first, then parents) to ensure accurate calculations. Only components that belong to the specified project can be recalculated through this endpoint.
