fix: update MCP tool/prompt/resource calls to use .fn attribute

FastMCP library changes now require calling decorated functions via the .fn attribute:
- Tools: @mcp.tool() functions return FunctionTool, call with tool.fn()
- Prompts: @mcp.prompt() functions return FunctionPrompt, call with prompt.fn()
- Resources: @mcp.resource() functions return FunctionResource, call with resource.fn()

Updated core files:
- view_note.py: read_note() → read_note.fn()
- read_note.py: search_notes() → search_notes.fn() (2 locations)
- tool.py: 6 MCP tool calls updated to use .fn
- recent_activity.py: recent_activity() → recent_activity.fn()
- project.py: project_info() → project_info.fn() with type ignore

Updated 100+ test files systematically to use .fn attribute and fixed mock targets.

All 869 tests now pass. Fixes view_note tool error in Claude Desktop.
