Function memory display and MCP server card redesign

This release surfaces function memory and instance counts on the source overview page and redesigns the MCP servers list on the plugin detail page to match the card pattern used elsewhere in the dashboard. It also includes infrastructure tuning for Fly machine resource limits and several bug fixes.

• Plugin detail MCP server card redesign #2552  - Redesigns the MCP servers list on the plugin detail page so each entry matches the card pattern from the MCP list page: the Network icon in the dot-pattern sidebar, name plus tool-count badge in the header, and the Public / Private / Disabled status indicator in the footer. Introduces a shared MCPStatusIndicator component used across MCP views. (Author: @bradcypert )

Bug fixes

• Fly machine resource tuning #2571  - Increases CPUs to 4 GiB and lowers the soft limit to 20% of the hard limit. (Author: @disintegrator )
• Assistant chat source tag #2575  - Tags chat sessions started from the Assistants page with X-Gram-Source: assistant instead of assistant-onboarding. Agent session logs now show assistant as the source for these sessions rather than conflating ongoing assistant chats with the onboarding flow. (Author: @simplesagar )
• Agent session conversation history #2557  - Fixed certain agent session side panel failing to load conversation history. (Author: @danielkov )
