## Summary
- Adds proper Latin1 encoding support, replacing CP1252 usage throughout the codebase
- Adds specialized, optimized string decoding methods with safe string filtering for each encoding type
- Filters invalid Unicode characters (C0/C1 control codes, non-characters) by removal rather than replacement since
the UO client renders nothing for these characters
- Fixes UTF-16 null terminator position handling to correctly advance by 2 bytes
## Changes
TextEncoding.cs
- Added SearchValues-based invalid byte/char detection for efficient filtering
- Added encoding-specific GetString methods: GetStringAscii, GetStringLatin1, GetStringUtf8, GetStringBigUni,
GetStringLittleUni
- Each method supports a safeString parameter for filtering invalid characters
- Little-endian UTF-16 uses direct memory cast for zero-copy decoding on LE systems
- Invalid characters are removed (not replaced with U+FFFD) since the client renders nothing for them
SpanReader.cs
- Added ReadLatin1() and ReadLatin1Safe() methods
- Rewrote encoding-specific read methods to use optimized TextEncoding.GetString* methods
- Fixed UTF-16 null terminator handling: position now correctly advances by byteLength (2) instead of 1
SpanWriter.cs
- Added WriteLatin1 and WriteLatin1Null methods
## Packet Updates
- Updated all packet code to use Latin1 encoding instead of CP1252
- Affected: account packets, equipment packets, menu packets, message packets, mobile packets, player packets, secure
trade packets, vendor packets, gump packets, book packets, mahjong packets
## Filtering Behavior
Invalid characters filtered in safe mode:
```
┌───────────────┬────────────────────────┐
│ Range │ Description │
├───────────────┼────────────────────────┤
│ 0x00-0x1F │ C0 control codes │
├───────────────┼────────────────────────┤
│ 0x7F │ DEL │
├───────────────┼────────────────────────┤
│ 0x80-0x9F │ C1 control codes │
├───────────────┼────────────────────────┤
│ 0xFFFE-0xFFFF │ Unicode non-characters │
└───────────────┴────────────────────────┘
```
Note: Surrogate pairs (0xD800-0xDFFF) are not filtered because proper validation requires context checking for paired
vs unpaired surrogates. The UO client renders nothing for these anyway.
## Test Plan
- All 631 Server.Tests pass
- Verified client rendering behavior using TestUnicodeGump command (pages 1-5)
- Confirmed U+FFFD, unpaired surrogates, and non-characters all render as blank in client
- Verified Latin1 characters (0xA0-0xFF) display correctly
- Verified C1 control codes (0x80-0x9F) are filtered and don't display

### Summary
* Adds support for size/style to dynamic/static builder.
* Drastically simplifies the dynamic/static builder api for AddHtml.
* Cleans up some legacy gump files.
New Jail System for MUO
----------------------------
Commands:
[jail [player] [reason] - Jail with time escalation per offense (5 to 120 minutes, GM only)
[unjail [player] - Manual release from jail regardless of time (GM only)
[jailinfo [player] - Check jail status and history (GM only)
[jailrecord - Checks their own jail record stats (player access)
Jail/Unjail can be found in the client view of a player in Admin Gump
Jail record gump, invoked with [jailrecord (30 second cooldown)
### Summary
- Puts back `EventSink.SocketConnect`.
- Reverts networking change to push the networking to a separate thread.
- Reverts changes to the firewall by removing the firewall queue.
- Fixes listeners not shutting down with the server.
- Fixes race condition causing connections to get stuck even after they are disposed.
> [!NOTE]
> **Developer Note**
> Networking has been reverted back to using the main thread instead of a background thread. This alleviated complexity and the requirement for concurrent queues all over the place.
### Summary
- `GenericEntityPersistence` is now a type of `GenericPersistence`. This allows developers to serialize both entities and non-entities in the same system. 🎉
- Each `SerializationThreadWorker` now allocates 1MB of heap for serialization _permanently_. If more memory is needed, that thread will double it's memory, not to exceed increments of 64MB.
- Several bugs with serialization introduced with the pure MMF implementation have been fixed.
- `BinaryFileReader` has been added back. 🎉
- Adds `world.useMultithreadedSaves` to allow disabling threaded saves.
> [!IMPORTANT]
> **Developer Note**
> The split file serialization has been deprecated and is no longer used. We have effectively gone back to the same file writing we had before the pure MMF implementation.

> **Developer Note**
> This code change will **completely move gumps out of the core**
### Summary
- Adds `GetGumps()` convenience which exposes methods to Find/Close/Send multiple gumps. This helper is a performance improvement by eliminating the Dictionary<Player, List> lookup for gumps.
### Summary
- Fixed a bug caused by a bad assumption. If `m_List[index]` is sparse and null values are casted, the server does not crash.
- Fixed a bug where `PooledRefList.ToList` extension method returned the wrong list size.
### Summary
- Moves `HonorSelf` gump to the Virtues folder.
- Renames `HonorSelf` to `HonorSelfGump`
- Makes `HonorSelfGump` a static gump.
- Changes the text in the gump to a cliloc.
- Collapses some of the checks for honoring to simplify the logic.
- Moves the player check higher to fix the wrong error message displaying when trying to honor damaged players.
