fix(licenses): add explicit xorm column names for all UpdateStreamConfig fields

xorm auto-maps CamelCase to snake_case by splitting on each
uppercase letter. MaintainerURL became maintainer_u_r_l instead
of maintainer_url, causing DB reads to return empty values.

Added explicit column name tags to all multi-word fields:
SupportURL, KeyPrefix, ExtensionName, DisplayName, ExtensionType,
MaintainerURL, InfoURL, TargetVersion, PHPMinimum, LicensingEnabled,
RequireKey, FeedVisibility, DownloadGating, StreamMode, CustomStreams.
