fix: pin strfry image and fix health check in CI (#7)

* fix: pin strfry image and fix health check in CI

Pin strfry Docker image to a specific digest to satisfy zizmor's
unpinned-images check. Replace broken health check (curl -sf fails on
HTTP 426 Upgrade Required) with status code check that accepts any
non-zero HTTP response as "ready".

* fix: use docker run for strfry to provide config file

The strfry image requires a config file at /app/strfry.conf. Service
containers can't mount files, so switch to docker run with a generated
default config via `strfry export-config`. Also dump container logs on
health check failure for easier debugging.

* fix: add strfry config for CI and mount into container

The strfry image requires a config file and export-config also needs
one (chicken-and-egg). Add a checked-in CI config with bind=0.0.0.0
(so the container is reachable from the host) and auth disabled.

* fix: mount tmpfs for strfry database directory

strfry needs ./strfry-db/ to exist for its LMDB database. Mount a
tmpfs at that path so the container can initialize the database.

* fix: set nofiles=0 in strfry CI config

The container's ulimit (65536) is lower than the default nofiles
setting (1000000). Setting nofiles=0 tells strfry not to attempt
changing the limit.

* fix: correct integration test assertions

delete_event: list-headers returns ok=false (NO_RESULTS) when no
headers remain after deletion. Use run() instead of run_ok() and
treat NO_RESULTS as a valid post-deletion state.

add_item_and_list: event_to_json does not extract the "r" tag as a
top-level "resource" field. Check the tags array directly for the
["r", url] entry.
