Add Soapstone param RPC methods

[goblock2021]

Summary

Adds 8 new gRPC methods to the Soapstone server, enabling remote access to Param Editor data via RPC.

New RPC Methods

Method	Description
ListParams	List all param names in the loaded project
DescribeParam	Get param metadata: type, row count, all field definitions
GetParamRow	Get all field values for a specific row by index
GetParamRows	Get all rows matching a given ID (handles duplicate IDs)
ListParamRows	List all row IDs, names, and indices (fast overview)
SetParamCell	Set a single cell value by row index
ExecuteMassEdit	Execute a Mass Edit script on the server's param data
ReloadParams	Hot-reload param changes to the running game process

Other Changes

• SoulsMemoryHandler.cs: Fix static ProcessOffsetBank dictionary leak — Terminate() now removes entries
• SoapstoneClient.cs: Fix gRPC channel shutdown fire-and-forget — now waits for pending shutdown before creating new
  connections
• SoapstoneServer.cs: Add Kestrel connection limits (MaxConcurrentConnections = 100, KeepAliveTimeout = 2 min)

I use them in conjunction with an external CLI script, which is very useful for data mining using LLMs. Additionally, it’s helpful to use external scripts to connect to SmithBox, make real-time modifications, and reload the changes into the game.
