fix: remove early prestige gates and improve quest unlock hints

- Remove prestigeRequirement from all original zone bosses (Shattered Ruins through Astral Void) — prestige gates now only apply to new endgame zones (Celestial Reaches onward)
- Show zone unlock hint on locked quests when the quest's zone is still locked, so players know what to do
- Switch quest reward numbers to use formatNumber instead of toLocaleString, fixing raw integer display for endgame values
