fix(microsoft-teams): rename public host to graph-mcp.decocms.com (#445)

* fix(microsoft-teams): rename public host to graph-mcp.decocms.com

Azure AD rejects reply URLs whose host contains brand tokens like
"microsoft" or "teams" with "Your reply url contains prohibited words
or prohibited domains." The old host tripped both. Switch the public
domain to graph-mcp.decocms.com so /oauth/callback can be registered.
