Radicale uses default DAV: namespace (no d: prefix) and CR: for CardDAV
instead of c:. Fixed all regex patterns to handle both variants:
- <href> and <d:href>
- <displayname> and <d:displayname>
- <CR:address-data> and <c:address-data>
- <C:calendar-data> and <c:calendar-data>
- </response> and </d:response>
Also fixed calendar discovery to match <C:calendar/> resourcetype
instead of looking for VEVENT string in the response.

URLs: mail.mcp.home.slohmaier.de, calendar.mcp..., etc.
No more path-prefix routing — each service has its own domain.
OAuth tokens stored in shared .active_tokens.json file so all
services can validate tokens issued by any service.

claude.ai uses the full OAuth Authorization Code flow, not client_credentials.
Flow: GET /authorize → auto-approve → redirect with code → POST /token
with code + code_verifier (PKCE S256).
Also fixes OAuth metadata URLs to use correct external scheme/host/prefix
via X-Forwarded-Proto, Host, and X-Forwarded-Prefix headers.

PDF, docx, xlsx, pptx etc. are returned as EmbeddedResource with
BlobResourceContents (base64 + mimeType). claude.ai processes these
client-side, same as Google Drive/Dropbox MCP connectors.
Fallback chain: text → image → embedded resource (binary).
MIME type guessed from extension when server returns octet-stream.
