Fix Hikvision default elevation configuration

[fraztto]

The Hikvision/Linovision registry reads timeout into default_elevation_deg.
Setting elevation to -4.5° and timeout to 9 seconds therefore uses 9° for mapped
preset moves. Read elevation from its own configuration key instead.

Rebased onto current develop (48ad5f1); the PR targets develop. Per review,
trim the parameterized cases to timeout-only and elevation-only for both aliases,
plus the mapped preset movement test. Startup ISAPI and movement execution are
mocked. All five focused tests and Ruff/format checks pass on Python 3.11.

New CI runs were triggered by the updated head. GitHub currently requires maintainer
approval for these workflows before execution.

The rebased full camera suite also passes locally: 82 passed, seven skipped.

Thanks @fraztto for catching this, the fix is correct and the tests cover it well (9 of the 11 fail with the old line restored).

One request before merging: please rebase onto develop and retarget the PR there. In this repo PRs go to develop, and main is behind it. The same bug is still on develop (registry.py:136), so the one-line change should apply cleanly.

Small optional nit: the parametrized cases could be trimmed to timeout only and elevation only, plus the preset move test. Not blocking.

The two failing checks look unrelated: test_engine.py fails with Invalid URL 'status' (engine package, untouched here) and the Docker build hits 404s on the Debian bullseye security mirror

Yeah, sorry about that. I've changed the base to develop. Thanks

Thanks for the fix !
