Run the live test suite on one event loop

[shauneccles]

Problem

The live suite shares one module-level GLinet client (and therefore one aiohttp session), but with current pytest-asyncio (>= 0.26, tested on 1.4.0) the custom session-scoped event_loop fixture is silently ignored and every test gets its own function-scoped loop. The session binds to the first test's loop, so every subsequent test fails with RuntimeError: Event loop is closed — the live suite is unusable beyond test_router_reachable.

Fix

• Mark the module with pytest.mark.asyncio(loop_scope="module") so all tests share one loop.
• Remove the obsolete event_loop fixture and the per-test @pytest.mark.asyncio markers (they would override the module loop scope back to function scope).

Test-only change; no library code touched.

Tested on real hardware

GL-MT6000 (Flint 2), firmware 4.9.0, pytest 9.1.1 / pytest-asyncio 1.4.0, non-disruptive tests only (-k "not set_enabled and not wireguard_start and not wireguard_stop and not tailscale_start and not tailscale_stop and not reboot").

Before (master):

test_router_reachable PASSED
test_login FAILED                 RuntimeError: Event loop is closed
test_router_info FAILED           RuntimeError: Event loop is closed
... (all 14 remaining tests fail the same way)
================== 15 failed, 1 passed, 6 deselected in 1.06s ==================

After (this branch):

test_router_reachable PASSED
test_login PASSED
test_router_info PASSED
test_router_get_status PASSED
test_router_get_load PASSED
test_router_mac FAILED            (macclone disabled on this unit)
test_connected_clients PASSED
test_wifi_ifaces_get PASSED
test_connected_to_internet FAILED (fw 4.9 returns {'detected': 0} without 'ip')
test_ping FAILED                  (fw 4.9 ping of 0.0.0.1 returns truthy)
test_wireguard_client_list PASSED
test_wireguard_client_state FAILED (no WireGuard client configured on this unit)
test_tailscale_status FAILED      (tailscale configured but disconnected: status 0)
test_tailscale_connection PASSED
test_tailscale_configured PASSED
test_tailscale_get_config PASSED
================= 5 failed, 11 passed, 6 deselected in 26.41s ==================

The 5 remaining failures are pre-existing assertion mismatches that depend on device configuration/firmware (they fail identically on master once the loop issue is fixed) — happy to follow up on those separately if useful.

Friendly final ping on this one — it's been open a few months with the rest of my queue, so I'm doing a tidy-up pass. Since filing it, my fork has continued as the independent glinet4 project (https://github.com/glinet4/glinet4, on PyPI as glinet4), which has absorbed this change along with the later work, so I no longer need it merged for my own use. If you'd still like it for gli4py I'm happy to refresh it against master — otherwise I'll close it in a couple of weeks to keep your PR list tidy. Thanks again for the original library!
