refactor: Move legacy deserialization into the .Migrations.cs partials (#2575)
Follow-up to #2574, which added a `.Migrations.cs` partial to `BaseWeapon`. Pure relocation — no behaviour change.

## The inconsistency

`BaseArmor` and `BaseClothing` already kept their pre-codegen `Deserialize(reader, version)` in a `.Migrations.cs` partial, but left the `OldSaveFlag` enum and the `GetSaveFlag` helper behind in the main class file — even though every call site is in the partial:

| Class | `Deserialize` | `GetSaveFlag` / `OldSaveFlag` | Call sites outside the partial |
|---|---|---|---|
| `BaseArmor` | already in partial | in main file | 0 of 26 |
| `BaseClothing` | already in partial | in main file | 0 of 12 |
| `BaseWeapon` | in main file | in main file | — |

`BaseWeapon` had all three still inline, with its new `.Migrations.cs` holding only a `MigrateFrom`.

## After

All three follow the same layout: `MigrateFrom` newest to oldest, then the pre-codegen `Deserialize`, then `GetSaveFlag`, then `OldSaveFlag`. That moves ~290 lines of legacy read path out of `BaseWeapon.cs` — the file that needed it most at ~3,900 lines — and leaves the main class files describing only how the type behaves today.

## Reviewing this

The diff is large and almost entirely noise, so it is probably not worth reading line by line. Two checks are stronger:

- **Nothing was lost or altered.** Across each `.cs` / `.Migrations.cs` pair, the multiset of non-blank source lines is identical to `main` except for one added comment (below). The relocation was done mechanically and asserted against that invariant rather than by hand.
- **Nothing about serialization moved with the code.** Running `ModernUOSchemaGenerator` after the move emits no new migration files.

The complete set of intentional additions:

- `using System;` in each of the three partials, for the `[Flags]` attribute (implicit usings are not enabled here).
- `// Version 9 (pre-codegen)` above `BaseWeapon`'s moved `Deserialize`, matching the marker `BaseArmor` and `BaseClothing` already carry. Version 9 is correct because `BaseWeapon.v10.json` is its earliest migration schema, so codegen began at 10.

Everything else is blank-line placement.

## Verification

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