UI/UX "Living Codex" 4/n: assistant features + emoji purge

- Replace all emoji icons (~26 instances) with Lucide icons across the app
  (DashboardPage, SessionSidebar, PlayerBoards, MyCharacterPanel,
  PlayerViewPage, EncounterTracker, CampaignsPage, HandoutControl,
  SessionControl, CharacterSheet, EncounterTipCard, ActionGuide)
- Expose real 5e race data in wizard (ASI/vision/traits instead of stub desc);
  add vision field to loadRaces5e return type
- Surface subclass descriptions after picking a subclass in the wizard
- Add per-class tips, race synergy notes, and ability/skill guidance in wizard
- New ActionGuide component: collapsible "What can I do on my turn?" in player view
- New SessionPrepCard: AI + fallback session hook generator on assistant page
- New NpcGenCard: AI + fallback quick NPC generator with "Add to campaign" action
- Inline NPC detail generator (wand button) on each NPC card in NpcsPage
- Quest hook generator button in QuestsPage header
- Condition tooltips in player party view (useConditionGlossary)
- Pass campaign.system through session snapshot so player view is system-aware
