Roslyn duplicate scans found the same code copied across layers:
- Data: the three browse sessions share BrowseSession<TPage, TSort>;
the remote clients share NestServerHttp (JSON options, If-Match,
error text).
- WinForms: five paged lists share BrowsePager for loading text,
navigation, sort glyphs and failure messages. The Add Drawings to
Release, Drawing Library and set browser dialogs now dispose their
browse sessions.
- Server: NestQueryRequest reuses DrawingLibraryRequest's helpers;
revision history queries share count and paging binds.
- Engine: RemnantPlateNester delegates to DefaultPlateNester;
CuttingPlanService reuses JointCuttingPlanSearch.Map.
- Core: LineArc and CleanHole lead-ins share LineArcApproach with
unchanged arithmetic order, so output is bit-identical.
- IO: Dxf.GetGeometry overloads share one reader; .nest JSON test
helpers move to NestArchiveJson.
Also fixes the production compiler warnings (CS8632, CS8603, CS0108)
and moves a test off an obsolete forwarding API.

The server becomes the system of record for shared drawings (cut type,
thickness, material and grade, customer, notes). Schema v4 adds `drawings`
(current row) and `drawing_revisions` (immutable) to the same SQLite file under
the existing monitor; the nest tables are untouched and a v3 upgrade keeps every
nest row byte-identical.
`/api/drawings` follows the nest revision contract: client-allocated ids,
If-Match on every existing-drawing write (428/400/409 with no state change),
archive instead of delete, and one transaction for promotion plus snapshot.
Geometry is an opaque package (a zero-plate .nest) the server never parses.
Enum fields accept single names only, because the JSON enum converter would
otherwise accept numbers and comma combinations. Material, grade and customer
filters match SharedListNames keys so spacing and case cannot split a drawing
family; thickness is stored and compared at four decimals.
Shared bounds live in OpenNest.Data so the client can refuse the same requests
before sending. If-Match parsing moves to one helper used by nests and drawings.
