refactor: Phase 3 — reorganize tests into module-mirroring subdirectories

Move 97 test files from flat tests/ into 13 subdirectories:
  tests/dashboard/   (8 files — routes, mobile, mission control)
  tests/swarm/       (17 files — coordinator, docker, routing, tasks)
  tests/timmy/       (12 files — agent, backends, CLI, tools)
  tests/self_coding/  (14 files — git safety, indexer, self-modify)
  tests/lightning/   (3 files — L402, LND, interface)
  tests/creative/    (8 files — assembler, director, image/music/video)
  tests/integrations/ (10 files — chat bridge, telegram, voice, websocket)
  tests/mcp/         (4 files — bootstrap, discovery, executor)
  tests/spark/       (3 files — engine, tools, events)
  tests/hands/       (3 files — registry, oracle, phase5)
  tests/scripture/   (1 file)
  tests/infrastructure/ (3 files — router cascade, API)
  tests/security/    (3 files — XSS, regression)

Fix Path(__file__) reference in test_mobile_scenarios.py for new depth.
Add __init__.py to all test subdirectories.

Tests: 1503 passed, 9 failed (pre-existing), 53 errors (pre-existing)
