Schema v5 stores each distinct drawing package once in drawing_packages,
keyed by SHA-256; revisions point at it, so details, settings, archive and
restore revisions add no blob. The v4 drawing tables are replaced outright
(no production library existed); nest tables are untouched.
Nesting settings (cut first, priority, rotation constraints, color) become
structured record fields (DrawingLibraryRecord.Settings), returned on every
read, filterable by cutFirst, editable through the metadata endpoint and
applied by LibraryDrawingInsert. Canonical packages now leave every
record-owned field at its default, so renaming or changing settings never
changes the package hash. Saving a nest drawing to the library carries its
settings into the record.
The desktop library browser gains a Cut first column and an Edit Settings
dialog that saves notes and settings as a new revision with the same package.

Saving a nest drawing to the drawing library now has a Linux-testable model,
DrawingLibrarySaveSession, ahead of the desktop dialog.
Prefill starts from the drawing's name and customer (the nest's customer when
the drawing has none), the nest's material, grade, thickness and units, and the
linked revision's cut type and notes when the drawing came from this server's
library, otherwise the operator's last-used cut type.
Duplicates follow D4: active drawings whose normalized customer, name, material
and grade and exact thickness, units and cut type match. The server only
narrows (a blank filter means "any" there, and LIKE does not collapse
whitespace), so every key is checked again on the client. The default is the
linked drawing when it matches, else the only match; several matches require
the operator to choose, and a linked drawing that no longer matches is offered
but never the default, so a thickness change cannot silently rewrite it.
Writes follow NestSaveSession: a new drawing's id is allocated before the
upload, and a save that fails without a definite answer stays pending. The
next save first looks for the revision it would have produced and adopts it
when the package hash and details match; a not-stored new drawing is retried
under the same id, never onto another drawing, and a revision someone else
saved meanwhile is a conflict. A definite refusal (409, old server, invalid
request) leaves nothing pending. On success the drawing's link points at the
saved revision; nothing else in the nest copy changes (D2).
RemoteDrawingLibrary now implements IDrawingLibraryStore, the read/write
surface the session needs, so tests can use an in-memory store.

Add from Drawing Library needs the same race-safe paging as the Database-mode
Open dialog: a generation counter so an older response never replaces a newer
one, cancellation after the superseding request is installed, and IsLoading
tracking only the latest request. `DrawingLibraryBrowseSession` mirrors
`NestBrowseSession` for library queries.
It starts filtered to the nest's material, grade and thickness, since that is
almost always what the operator wants and a mismatch drops cut pins anyway
(D3). "Show all" lifts the filter. A nest with no thickness filters by material
only, and the empty-result text tells the operator when the nest filter, rather
than an empty library, is why nothing is listed. Archived drawings stay hidden.
`IDrawingLibrary` is the read side the session and the add flow use, so both
are testable with fakes; `RemoteDrawingLibrary` implements it.

RemoteDrawingLibrary covers upload, query, get, package download, revisions,
revision packages, guarded package/metadata updates, archive and restore. It
checks the shared bounds before sending, refuses oversized or inconsistent
pages, and verifies that the server stored the exact package it sent.
A 404 on the library routes means the server predates them: the client raises
ServerTooOldException and never falls back to another store. Because a 404 for
one drawing is ambiguous, it probes the query route before deciding between
"unknown drawing" and "server too old". Conflicts raise
DrawingLibraryConflictException carrying the current record, which the save
flow needs to offer a reload or the next revision.
