fix: resolve all CI failures (linkcheck + functional test)

- CHANGELOG.md: update tobixen/plann issue links to pycalendar/plann
  (issues 14 and 16 return 404 after repo rename)
- .lychee.toml: exclude xandikos.org (intermittent 502, not under our control)
- tests/test_functional.py: catch NotImplementedError from journal search
  (xandikos does not support CalDAV REPORT for VJOURNAL)
- tests/test_functional.py: reload todo1/todo2 before _adjust_relations reset
  to get fresh ETags after _check_for_panic modified those objects on the server

prompt: pull request 35 still fails
