c720e354d2 service/ldn: Implement SetProtocol and SetWirelessAudioPolicy commands 
Adds support for LDN service commands introduced in firmware 20.0.0+:
- Command 105: SetWirelessAudioPolicy (stubbed)
- Command 106: SetProtocol

This enables ACNH Update 3.0 and other games using newer SDK versions
to properly initialize LDN for local multiplayer functionality.

a1b317a15e fix: add Module 56 error support and improve error handling 
- Add Module56 to ErrorModule enum for error code 2056-2306
- Add Module 56 error handling in fatal error reporting
- Define Module 56 error codes in ldn_results.h
- Improve error reporting for unknown modules

This allows the emulator to properly handle error code 2056-2306
reported by Minecraft and other games, preventing undefined
behavior when encountering unknown module errors.

68a8b07f78 feat(ldn): Implement missing Account and LDN services from SwitchBrew documentation 
Implements 150+ missing functions across Account (acc:*) and LDN (ldn:*, lp2p:*)
services based on official SwitchBrew documentation.

Account Services (acc:su, acc:e, acc:u0, acc:u1, acc:e:u1, acc:e:u2, dauth:0):
- Add 70+ missing functions including notifiers, async operations, and OAuth procedures
- Implement GetUserRegistrationNotifier, GetUserStateChangeNotifier, GetProfileUpdateNotifier
- Add thumbnail management (LoadSaveDataThumbnail, GetSaveDataThumbnailExistence)
- Implement user management (DeleteUser, SetUserPosition, CancelUserRegistration)
- Add Nintendo Account procedures (CreateFloatingRegistrationRequest, etc.)
- Implement device migration functions (19.0.0+, 20.0.0+)
- Add debug functions for user qualification and token cache management

IManagerForApplication/SystemService (19.0.0+ compatibility):
- Rename LoadIdTokenCache (cmd 3) to LoadIdTokenCacheDeprecated
- Add new LoadIdTokenCache (cmd 4) with updated signature
- Add GetNintendoAccountUserResourceCache (cmd 136)

LDN Services (ldn:m, ldn:s, ldn:u):
- Add 80+ missing functions across all LDN interfaces
- Implement CreateClientProcessMonitor (cmd 1) for ldn:s and ldn:u (18.0.0+)
- Create IClientProcessMonitor service with RegisterClient function
- Implement IMonitorService functions (GetNetworkInfoForMonitor, GetIpv4AddressForMonitor, etc.)
- Implement ISystemLocalCommunicationService (GetState, Scan, Connect, Initialize, etc.)

LP2P Services (lp2p:app, lp2p:sys, lp2p:m):
- Implement ISfService functions (Initialize, Scan, CreateGroup, etc.)
- Implement ISfServiceMonitor (GetGroupInfo, GetMembers, AttachJoinEvent, etc.)
- Implement ISfMonitorService (GetLinkLevel)

Technical Changes:
- Change non-domain (C<>) to domain (D<>) functions in LDN to fix crashes
- Add enhanced error messaging to cmif_serialization.h for debugging
- Create client_process_monitor.cpp/.h for IClientProcessMonitor
- Add concrete async context implementations (EnsureSignedDeviceIdentifierCacheAsyncInterface, etc.)
- Add Kernel::KReadableEvent forward declarations

All functions properly stubbed with appropriate logging for future implementation.

References:
- https://switchbrew.org/wiki/Account_services
- https://switchbrew.org/wiki/LDN_services

Fixes 'Pokemon: Legends Z-A' LDN initialization crashes and improves compatibility
with games using Account and Local Network services.
