Claude a3b668d32f Treat an empty device_info as "nothing new", not as "forget what you know"
Every web and BrightSign player nulled seventeen of its own device columns every five minutes.

The browser player's refresh-register sends `device_info: {}` on a 300-second timer — it has nothing
new to report, it just wants a fresh playlist. But `{}` is truthy, and applyDeviceInfo is a blind
full-row overwrite with no per-field presence check, so it bound undefined for every column.
better-sqlite3 stores undefined as NULL rather than throwing, so the write succeeded and the row was
quietly emptied: android_version, app_version, screen_width/height, render_*, ota_status and
attempts, tier, the four capability flags and the four volume/brightness columns.

Android never hit it, because it always sends the full object. So this degraded exactly the client
family that cannot be inspected any other way — a browser player has no adb, and the dashboard row
is all there is. Fleet view, resolution diagnostics and any version-based logic read blank for them,
which also makes evaluating a browser-based platform look worse than it is.

The surrounding code already anticipates the refresh shape: recordReconnect and persistIdentity are
both gated behind `if (!isPlaylistRefresh)`. This call was the one that was not.

5 tests, including one pinning the driver behaviour the bug depended on — undefined binds as NULL
rather than throwing, which is why this was a silent five-minutely wipe instead of a loud error.
