fix: Consolidate PlayerConstructed onto Item, stamped by the craft system (#2574)
Follow-up to #2573. That change made `SmallBOD.EndCombine` require a player-crafted item, but it could only read provenance off `BaseArmor`, `BaseWeapon` and `BaseClothing`, because those are the only three classes that track it — hence the hand-enumerated `armor?.PlayerConstructed ?? clothing?.PlayerConstructed ?? weapon?.PlayerConstructed ?? false`.

The gap is structural rather than cosmetic. `PlayerConstructed` is set inside each base's `OnCraft`, so it can only ever reach types implementing `ICraftable`. Most craftables do not — the tinkering catalogue alone is largely plain `Item` subclasses — so any rule keyed on "was this actually crafted" has nothing to key on for those types.

## What changed

Provenance moves to `Item` and is stamped centrally in `CraftItem`, immediately after the item is constructed and before the `ICraftable` dispatch, covering both the AOS and T2A craft paths. The three `OnCraft` overrides drop their now-redundant assignment and inherit `Item`'s property, so no call site outside them changes — `Resmelt` and `SalvageBag` still read `armor.PlayerConstructed` and still compile unchanged. `SmallBOD`'s three-way null-coalescing chain collapses to `item.PlayerConstructed`.

`OnCraft` is only ever invoked from `CraftItem` (the other three call sites are `base.OnCraft` chaining), so removing those assignments has no other reachable effect.

## Storage cost: none

`Item`'s `SaveFlag` word is written as a fixed-width `int`, not an encoded one, so occupying bit `0x08000000` changes no record lengths. Items that are not player-constructed serialize byte for byte as before, and crafted ones differ by a single bit in a field already being written.

`Item` itself needs no version bump: a bare `SaveFlag` bit is self-describing, so records written before it existed lack it and read `false`.

## Version bumps

The three content classes do need one, since removing a serialized field changes their layout:

| Class | Version | Field removed |
|---|---|---|
| `BaseArmor` | 9 → 10 | 24 (was last, nothing renumbered) |
| `BaseClothing` | 7 → 8 | 7 (fields 8–10 shift down) |
| `BaseWeapon` | 10 → 11 | 26 (fields 27–30 shift down) |

Each gets a `MigrateFrom` for its previous version that assigns the old bool to the inherited property, so existing crafted armour, weapons and clothing keep their provenance across the upgrade. `Item.Deserialize` runs first and reads the absent bit as `false`, then the migration overwrites it — the generated `Deserialize` calls `base.Deserialize` before dispatching, so the ordering holds. `BaseWeapon` had no migrations file and gains one.

The renumbering is not stylistic: the generator requires contiguous field ordering and rejects a hole with `SG3005: Expected field 'Crafter' with order 7 but found 8`.

New schema JSONs (`BaseArmor.v10`, `BaseClothing.v8`, `BaseWeapon.v11`) are generated by `ModernUOSchemaGenerator` and committed alongside.

## One thing worth a second opinion

The new property is a plain auto-property on `Item`, so it does not call `this.MarkDirty()` the way the codegen setters it replaces did. `MarkDirty` is currently a no-op (`// TODO: Add dirty tracking back`) and no property in `Item.cs` calls it, so this matches the file as it stands — but it is worth noting if dirty tracking comes back.

## Verification

Full solution builds in Release with 0 errors and 0 warnings; 1516 tests pass (815 `Server.Tests`, 701 `UOContent.Tests`).
