Pull request overview
This PR introduces ICPC (ACM) contest mode to the platform, implementing the ICPC ranking algorithm alongside the existing IOI mode. It also makes the IOI 2013 ranking algorithm selectable, which previously existed but was not user-accessible.
Changes:
- Implemented ICPC scoring algorithm with penalty-based ranking (first AC time + penalties for wrong submissions)
- Added contest mode selector and penalty value configuration in contest management UI
- Added score type selector for problems in IOI mode (IOI2017 vs IOI2013)

This PR introduces a new contest mode, ICPC, with the primary change being the implementation of the ICPC ranking algorithm.
Additionally, it makes the IOI 2013 ranking algorithm optional.
Although this algorithm already existed in the codebase, it was not previously selectable
