feat(14-06): convert route tests + MCP tests to async PGlite

- All 8 route test files: async createTestApp(), async beforeEach
- MCP tools test: await createTestDb(), await getCollectionSummary()
- Fixed MCP tool files: added await to all service calls in items, categories, threads, setups tools
- Fixed MCP collection resource: made getCollectionSummary async
- Fixed MCP index.ts: await getCollectionSummary call
- Increased test timeout to 30s in bunfig.toml for PGlite WASM overhead
- Zero SQLite references remain in tests/
