[MoM] Jmathify and variable-ize power learning times

[Standing-Storm]

Summary

Mods "[MoM] Jmathify and variable-ize power learning times"

Purpose of change

Someone suggested that intelligence and proficiencies should make learning new powers easier, and that's a completely reasonable request.

Implements #73519

Describe the solution

Replace the numeric values in the insight EoC and the variable power-learning EoCs with Jmath and variables. Variables are initiated on game start and as a one-time EoC that runs for existing games.

The values are the same as previously (tier 1 power EoCs run every 12 to 24 hours, insight is gained once every 12 to 168 hours, etc), but are now affected by various factors. Insight is gained 3% faster per point of intelligence above 10 (capped at 60% faster at 30 Intelligence) and 5% faster per point of Metaphysics above 5. The power-learning EoCs for each path run 3% faster per point of intelligence above 10 (capped at 60% faster as before) with a flat 20% bonus if you know the insight proficiency for that path.

Insight proficiencies have been reduced to requiring 32 h of practice.

Testing

EoCs still run, some observed times were lower than previous possible minima.

Loaded into a game made before the changes, EoCs still functioned.

Additional context

Man it sure is fun to test things in a mod based on unpredictable outcomes
