Adds src/app/camera-queries.ts: React Query hooks over our own routes,
with each camera's queries keyed ['camera', id]. The camera card,
snapshot polling, login form and network scan use these hooks instead
of hand-rolled fetch/useEffect state (vrek iss-2fm6x2y, iss-ksxmctm,
iss-m032zwq, iss-8hfq2y2).
- Snapshot polling pauses in hidden tabs, never overlaps a slow
frame, and stops after a failure until Retry. Each frame's object
URL is created and revoked in one effect, so none leak under Strict
Mode.
- Saving or forgetting a login resets only that camera's queries.
- New "Forget saved login" action, shown for stored logins.
- Fix: a scan timeout typed below 1 s now clamps to 1 s instead of
falling back to 5 s.
Adds jsdom component tests (test/dom.tsx helpers): 93 tests, line
coverage 54.3%. Refreshes the vrek export.
