Two follow-ups from this week's drafts. UserAgents is an empty list when the engine does not record the matched User-Agents, as the specification's default says, and the Device Detection web example test sends no usage data from CI.

Closes #163. Closes #150.

Problem

1. UserAgents with the option off. With update_matched_useragent=False the native results still give one matched User-Agent per result, each empty, so UserAgents was [""] (one empty string, which #145 lists once), and test_turned_off_leaves_user_agents_empty expected empty strings (#163).
2. Usage data from CI. test_onpremisegettingstartedweb.py builds the on-premise web example from its config.json, which shares usage, and closes its Pipeline when the tests end, so every CI run sent real usage data (#150).

What the specification says

The match metric table in device-detection-on-premise.md lines 466 to 476 at 706de1f0 gives UserAgents the default value [] and says it is "Populated when the Update Matched User Agent configuration option is on".

What changed

1. DeviceDetectionOnPremise keeps whether it records the matched User-Agents, being on unless update_matched_useragent is given as false, as the native default is on, and SwigData gives UserAgents as [] when it does not. The test now expects [].
2. test_onpremisegettingstartedweb.py replaces requests.post from the start of its tests until the example's Pipeline has closed, so what usage sharing sends goes to the stand-in. Test only.

Before you upgrade

• With update_matched_useragent=False, UserAgents is [], where it was [""].

How it was verified

• Red, full build 43652293282 on b47570f, the UserAgents test alone on rc 8d05fe2. In all ten jobs only test_turned_off_leaves_user_agents_empty failed, "1 failed, 83 passed" in the on-premise Device Detection tests.
• Green, full build 43654803703 on the head 315e305, from rc 28e5bf2, is green. Its ten Build and Test jobs, Python 3.10 to 3.14 on Ubuntu and Windows, each passed, with test_update_matched_useragent.py (4 tests) and test_onpremisegettingstartedweb.py (6 tests) passing in each. The 11 Setting 'PullRequestSha' lines all name 315e305, and Configure printed "Left out 5 macOS entries". macOS was left out of this draft's full build under the 9 November decision. The rc head is built with macOS before it merges into main.
• The web example test change is a test only, so it has no red. It stands in for requests.post, which no test can see being called for real.

What it releases

fiftyone_devicedetection_onpremise and its dependants, which Monday's release plan releases already.

What remains

Nothing.
