Make the test suite fully green; drop the migration review doc

Resolve the 4 pre-existing failures that predated this branch (broken
auto-generated scaffold stubs + one test for an unimplemented feature):

- DsnAuthenticationService: support GlitchTip's ?glitchtip_key= query param
  alongside Sentry's ?sentry_key= (the app targets Sentry/GlitchTip compat).
  The existing test now passes against a real implementation.
- settings_controller_test: replace the scaffold stub (wrong *_url helpers) with
  real tests — index renders; update persists + redirects; invalid ntfy_url is
  rejected. Exercises the alerting settings added in #14.
- oidc_logout_controller_test: replace the scaffold stub with a real test of the
  backchannel-logout endpoint rejecting a tokenless request.

Suite is now 149 runs, 0 failures, 0 errors.

Also remove SQLITE_MIGRATION_REVIEW.md — every item (#1–#18) plus the duckdb-gem
cleanup is done and committed, so the action list has served its purpose.
