feat(desktop): show a server nest's MaterialLedger holds and closeout note

Server nests in Database mode get a read-only status bar label comparing their
open MaterialLedger holds with the sheets they cut, e.g. "Ledger: 2 of 4 held,
2 short". Nothing writes to the ledger and nothing waits on it.

- MaterialLedgerClient.GetHoldsAsync reads GET /api/stock/holds?openNestNestId=
  with the closed LedgerHoldsResult set; unknown status strings are kept. The
  request plumbing is shared with GetStockAsync.
- LedgerHoldSummary (OpenNest.Data) counts Proposed/Approved/Released/
  AwaitingCloseout holds against the plate quantities, skipping the trailing
  empty plate as /sheets does.
- NestHoldStatus refreshes on server open, after save, after storage or
  Options changes and on label click; it never polls. The tooltip lists holds
  in nest units. File-mode, unsaved and ledger-less nests show nothing.
- Setting Has Been Cut in Nest Info with holds still open shows a non-modal
  note linking to {ledgerUrl}/Nests/{id}. Posting is not gated.

A file without it, or with a malformed or non-positive value or an unknown source,
reports `null`.
### MaterialLedger holds (desktop)
MaterialLedger creates one hold per physical sheet of a server nest, from
`/sheets`, and stores the nest's ID. The desktop shows those holds read-only; it
never creates, approves or closes them, and nothing waits on the ledger.
**Where.** A status bar label after the material label, only for a nest saved to
the server in Database mode (`Document.RemoteId`, not a first save) while
Tools > Options > MaterialLedger has a URL ([setup](automatic-nesting.md#stock-from-materialledger)).
File-mode nests, unsaved nests and PCs without a ledger show nothing. The tooltip lists
each hold: item code, size in the nest's units, location code and status.
**When.** The holds are read when a server nest opens, after each Save, after the
storage mode or Options change, and when you click the label. The status bar never polls.
Each read uses `MaterialLedgerClient.GetHoldsAsync` (`GET /api/stock/holds?openNestNestId=`,
`X-Api-Key`, 5 s), whose result is `NotConfigured`, `Unreachable(reason)`,
`Unauthorized` or `Ok(holds)`. A newer read replaces an older one still running.
**Summary.** `LedgerHoldSummary` (`OpenNest.Data/MaterialLedger/`) compares the
open holds with the sheets of the last open or save: the sum of plate quantities,
skipping the trailing empty plate as `/sheets` does. Proposed, Approved, Released
and AwaitingCloseout holds are open. Closed, cancelled, exception and unknown
statuses are listed but not counted; unknown status strings are kept as sent.
| Holds | Label |
|-------|-------|
| One open hold per sheet | `Ledger: 4 of 4 sheets held` |
| More open holds than sheets | `Ledger: 4 of 4 sheets held, 1 extra` |
| Some sheets without one | `Ledger: 2 of 4 held, 2 short` |
| None open | `Ledger: no holds`, or `Ledger: no open holds (3 closed)` |
| No answer or key rejected | `Ledger: unavailable` (the tooltip gives the reason) |
The label prefix is `Ledger:` rather than `Material:` so it is not confused with the
nest's material label beside it.
**Has Been Cut.** When Nest Info changes the status to Has Been Cut, the desktop
rereads the holds. If any are still open, it shows a non-modal note, "Close out N holds
in MaterialLedger", with a link to `{ledgerUrl}/Nests/{id}`. Closeout happens there.
The note never blocks the dialog, save or post, and posting is not gated on holds.
### Generated nest names
**File > New** names a nest `N<yy>-<seq>` (`OpenNest.Data.NestNames`): the
