Add player character management feature

Persistent player character templates (name, AC, HP, color, icon) with
full CRUD, bestiary-style search to add PCs to encounters with pre-filled
stats, and color/icon visual distinction in combatant rows. Also stops
the stat block panel from auto-opening when adding a creature.
