refactor(server): extract the loops routes into routers/loops.py (R3) (#839)

Third router. Practice loops (saved A/B regions per song): GET/POST/DELETE
/api/loops, meta_db-only (0 setattr targets, 0 helpers to relocate per
router_scan.py). Bodies verbatim; @app -> @router, meta_db -> appstate.meta_db.
include_router at the original site; 143-route table identical to origin/main.

server.py: 9,337 -> 9,301.

No test retargeting (test_demo_mode only names the paths in middleware regexes).
Verified: pyflakes clean; route table identical; pytest 2398 passed; packaging
guard green; eslint 0; boot smoke drives POST (auto-names "Loop N") / GET / DELETE
/ missing-fields error, and demo mode 403s both writes while allowing the read.

### Added
- **`routers/` — extracting `server.py`'s route layer, cheapest-first (R3).** Each PR moves a cohesive route group into a `fastapi.APIRouter` under `lib/routers/`, mounted with `app.include_router(...)` at its original site (FastAPI matches in registration order; the full route table stays byte-identical). Bodies are verbatim — only the decorator receiver (`@app` → `@router`) and singleton reads (`meta_db` → `appstate.meta_db`, resolved at call time) change. So far: `audio_effects` (5 routes), `artist_aliases` (5 routes — the Tidy-up/P4 alias overrides). The next cut is picked by a dependency-closure scan that ranks groups by how many `monkeypatch.setattr(server, …)` targets they'd drag along.
