feat(morality): fleshed out morality system

[JARVIS-AT-ROOTCAUSED]

Summary

• overhaul morality data model and persistence (score + standing + last-updated timestamp)
• add configurable morality action weights and score clamping
• add daily decay toward neutral (forgiveness over time)
• add /morality command suite: status, top, add, set, reload
• register new command + admin permission in plugin.yml
• update Morality config format with settings, actions, and bounds

Behavior Changes

• player alignment now resolves from threshold bounds via floor-matching
• morality changes now emit clearer feedback messages
• killing an evil player rewards morality; killing non-evil players penalizes morality

Notes

• supports legacy uuid:morality lines when loading old playerdata
• writes new format as uuid:morality:lastUpdatedEpochSeconds
