"""Strict Atlassian (Jira + Confluence) MCP OAuth/tool fakes for Playwright E2E.

Jira and Confluence share one hosted Atlassian Rovo MCP server
(``https://mcp.atlassian.com/v1/mcp``) and one OAuth surface. Because the MCP
OAuth/runtime dispatchers are keyed by URL, a single handler here serves both
connectors; production keeps their tool sets disjoint via each service's
``allowed_tools`` curation. The OAuth ``redirect_uri`` substring is therefore
relaxed to the shared ``/api/v1/auth/mcp/`` prefix so both the
``.../mcp/jira/...`` and ``.../mcp/confluence/...`` callbacks validate.
