chore: upgrade fastmcp to v3.32.0

Upgrade fastmcp dependency from 1.27.7 to 3.32.0 to use the latest version with improved features and bug fixes.

Updated all tool implementations to be compatible with fastmcp v3 API changes:
- Changed Tool type signature from Tool<undefined, ...> to Tool<FastMCPSessionAuth, ...>
- Updated execute functions to accept context parameter (params, _context)
- Added FastMCPSessionAuth type imports
- Added changesets for this patch
