Release LoadGen Api, Appliance and MCP Server: 1.0.0.11800

LoadGen General

• Fixed Swagger UI failing to load with a JSON parser error caused by enum values being rendered as non-printable characters; enum names now remain readable on the wire and in HTTP response headers.

LoadGen Api

• Plugin and PowerShell Uptime Checks via the API : Uptime checks of types PowerShell and CustomPlugin (and the new built-in WebHeader and WebRegex types) can now be created and updated via the API. The provider key, script path, assembly path, entry type name, and parameters fields are now accepted on create, update, and Test & Inspect endpoints; the list endpoint returns the provider key so the frontend can surface a plugin badge without an additional fetch.
• Uptime Modular Check System : Phase 1 introduces a hierarchical group and catalog taxonomy on uptime checks (e.g. Database/SQL/Microsoft), a new catalog endpoint group (/uptime/catalog, /uptime/catalog/{key}, /uptime/groups), and group/catalog filters on the check listing. Phase 2 adds 15 BCL-only built-in check types across Network (TCP, UDP, ICMP, DNS Resolve, DNS Authority, WHOIS, NTP, SMTP, FTP, SSH), Web (Header, Regex, TLS Cipher, HSTS), and Certificate (chain) categories. Phase 3 introduces a stable plugin contract (IUptimeCheckProvider), a PowerShell script executor, and a plugin adapter that catches every plugin exception so a bad plugin cannot bring down the worker. Phase 4 wires a DLL plugin loader with isolated assembly load contexts, SHA-256 manifest verification, path-traversal rejection, per-provider group gating, and per-plugin execution timeouts.
• Fixed the uptime monitoring service crashing after the new modular check system landed, which had taken uptime monitoring down with repeated gRPC errors
• Fixed Citrix, RDP, VMware, WVD, and Full Agent monitoring sessions failing instantly because agents were incorrectly told to use "LocalHost" as their master IP; agents now correctly honour the master IP supplied by the API.
• Fixed Swagger tag ordering and domain membership so the Cockpit and Uptime configuration tags now appear in their intended sections and parent domain documents
