refactor(ui): monologue display — multi-line architecture per Tyre review (#122)

Rewrites the monologue display system per Tyre architecture review (Sprint 14):

Rendering:
- Up to 3 simultaneous visible lines (VBoxContainer, dynamic node creation)
- Lines created programmatically as MarginContainer > RichTextLabel per slot
- Percentage-based anchors: 5% left, 75–98% vertical (25% area from bottom), 50% max width
- Z-layer 7 in UILayer (CanvasLayer 20, D-049)

Queue:
- 5-entry priority queue; highest priority drains first
- On overflow: incoming line replaces lowest-priority queued entry if it outranks it
- Lower/equal priority incoming lines silently dropped when queue full

API:
  show_monologue(text, duration, priority=2, is_urgent=false)
- Replaces old (text, duration, character_type) signature
- main.gd passes priority and is_urgent from MonologueEvent fields
- Confrontation monologue: priority=3, is_urgent=true (D-063)

Colour:
- Reads GameState.lattice_profile at render time (D-032)
- lattice_augmented (detective): standard #d0d4e0 / urgent #e0e8f8
- lattice_baseline (smuggler): standard #d8d0c4 / urgent #f0e4d4
- Fallback for unknown profiles; no crash

Stagger: 0.15s between consecutive fade-ins (spec §5.4)
Opacity: standard 0.85, urgent 1.0; bloom deferred

GameState: adds lattice_profile field, parsed from snapshot

Tests: 27 gdUnit4 test cases — queue order, priority drop, overflow, stagger,
no-overwrite (P0 #477), BBCode output, palette selection, slot lifecycle
